The Potential of Mucor irregularis Isolated From Fruits in Producing Microbial Lipid

2024-03-31T04:25:25+00:00

In this present study, potential oleaginous Mucorales fungi that have been isolated from fruits from local markets in Sleman, Indonesia, were screened for lipid production. A total of six fungal cultures were isolated and screened using a semisynthetic medium with glucose as a carbon source and a limited nitrogen supply. The highest lipid content was observed in isolate JR 1.1, up to 43.46% and 3.28 g/L lipid yield. Therefore, it was selected for molecular identification and fatty acid analysis. The result showed that JR 1.1 was identified as Mucor irregularis. The fatty acid profile of JR 1.1 showed 16.89% palmitoleic acid, 4.85% oleic acid, 45.22% linolenic acid, 30.79% gamma-linolenic acid, and 2.25% other fatty acids. It can be concluded that M. irregularis JR 1.1 is a potential strain to be used as a lipid producer for biodiesel feedstock. Further studies are recommended to optimize lipid productivity and improve fatty acid composition.

Antibiofilm Efficacy and Mode of Action of Etlingera elatior Extracts Against Staphylococcus aureus

2024-03-31T04:25:04+00:00

Staphylococcus aureus represents a major bacterial human pathogen that causes a wide variety of clinical manifestations. Various medicinal plants have been used to control its infection, however, the effect of Etlingera elatior on S. aureus biofilm is still uncertain. Thus, the objective of this study was to evaluate the antibacterial and antibiofilm efficacy of E. elatior extracts against S. aureus. Phytochemical screening was carried out to determine the presence of phenols, tannins, saponins, and alkaloids in different extracts (acetone, methanol, ethanol, and aqueous) of E. elatior. Antibacterial activities were determined by disk diffusion assay, minimum inhibitory concentration assay (MIC), and minimum bactericidal concentration assay (MBC) while antibiofilm activities were determined by crystal violet assay and Fourier-transform infrared (FTIR) spectroscopy. All the extracts were found to contain phenols, tannins, saponins, and alkaloids. Only acetone extract showed a high amount of saponins. Among all the extracts, acetone extract showed the widest inhibition zone (21.23±0.2 mm), lowest MIC (20 mg/mL), and lowest MBC (50 mg/mL) values. The acetone extract also showed the highest antibiofilm activities at all biofilm stages (6 hr: 12%-31%; 12 hr: 20%-36%; 18 hr: 27%-32%; 24 hr: 5%-46%). Further analysis with FTIR spectroscopy revealed spectral changes associated with proteins (1700–1400 cm^-1), phospholipids, and polysaccharides (1300–700 cm^-1) in S. aureus biofilm following the treatment with 200 mg/mL of E. elatior extracts. In conclusion, E. elatior is a potential source of antibacterial and antibiofilm agents to control S. aureus infections. Changes in the composition of proteins, phospholipids, and polysaccharides may mediate the biofilm inhibition by E. elatior extracts. The acetone extract of E. elatior may be useful for various applications such as antimicrobial topical cream and wound dressing.

An in silico Approach For Identification of Potential Therapeutic Targets For Cancer Treatment From Celastrus hindsii Benth

2024-03-31T04:25:08+00:00

Celastrus hindsii Benth., a medicinal plant celebrated for its traditionally medicinal and practically therapeutic properties, has been used for generations in Vietnam to support the treatment of ulcers, tumors, and inflammation. The difference between several phenotypes, primarily identified as Broad Leaf (BL) and Narrow Leaf (NL), has been clarified by convincing scientific evidence through our previous proteomics study, which also revealed several bioactive proteins and peptides. Therefore, based on the findings, this study further investigated their therapeutic properties using a bioinformatics tool (BLASTP) and analyzing literature data. The results showed the distinguished variations in protein profile between the NL and BL proteomes and revealed five significant proteins with therapeutic properties. Of these, three proteins can have anti-tumor and anti-inflammatory activity and have been proven effective in cancer treatment. Therefore, C. hindsii, particularly the BL phenotype with elevated levels of therapeutic proteins, could be a promising plant candidate for future intensive research and applications for cancer treatment.

Phylogenetic Relationship of Diadema: Emphasis on The Two Distinct Clades of D. Setosum With The Inclusion of Long Spine Black Sea Urchin From Malaysian Borneo

2024-03-31T04:25:16+00:00

Diadema urchins (family Diadematidae) are ecologically important bioindicators of coral reef ecosystems and seagrass beds. Diadema urchins which are widely distributed and broadcast spawners, have been frequently utilized as model invertebrate species for zoogeography research of the Indo-West Pacific region. So far, Malaysian Borneo, located at the geographic center of Maritime Southeast Asia, has been under-sampled. This study aims to fill this sampling gap and provide the first record of Diadema setosum from Malaysian Borneo using genetic diagnostics to conclusively establish the clade-level identity of the species. According to Cytochrome Oxidase I gene analysis, Diadema is monophyletic. Seven species of Diadema namely Diadema palmeri, Diadema clarki, Diadema mexicanum, Diadema antillarum, Diadema paucispinum, Diadema africanum, and Diadema savignyi, formed their subclades with strong bootstrap values, demonstrating interspecific variation. The findings of this study provide further evidence for the presence of two distinct monophyletic clades, with all D. setosum individuals forming a monophyletic clade that later split into two distinct subclades, dividing Red Sea population (D. setosum-b) and Indo-West Pacific populations (D. setosum-a), supported by a significant genetic divergence value ranging from 6.3% to 9.1%. This study also revealed notable levels of nucleotide and population subdivision between the D. setosum from the Indo-West Pacific and the Red Sea populations (Nst = 0.891; Fst = 0.886) with a low number of migrants per generation (Nm = 0.065). This may suggest geographic isolation due to ecological factors preventing each other from surviving in the territory of the other, or that the two clades of D. setosum were a separate species. Additional morphological and molecular analysis is required in the future to ascertain the level of divergence and further resolve the taxonomic confusion within the genus Diadema.

Medium Optimization for Biobutanol Production From Palm Kernel Cake (PKC) Hydrolysate By Clostridium saccharoperbutylacetonicum N1-4

2024-03-31T04:24:50+00:00

The study aims to optimize the medium composition for biobutanol production using a Palm Kernel Cake (PKC) hydrolysate by Clostridium saccharoperbutylacetonicum N1-4. Various nutrient factors affecting biobutanol production were screened using the Plackett-Burman design. These factors included: NH₄NO₃, KH₂PO₄, K₂HPO₄, MgSO₄.7H₂O, MnSO₄.7H₂O, FeSO₄.7H₂O, yeast extract, cysteine, PABA, biotin, and thiamin. The results were analyzed by an analysis of variance (ANOVA), which showed that cysteine (P=0.008), NH₄NO₃(P=0.011) dan yeast extract (P=0.036) had significant effects on biobutanol production. The established model from the ANOVA analysis had a significant value of P_model>F = 0.0299 with an F-value of 32.82 which explains that the factors can explain in detail the variation in the data about the average and the interpretation is true with an R² value of 0.993. The estimated maximum biobutanol production was 10.56 g/L, whereas the optimized medium produced 15.49 g/L of biobutanol. Process optimizations with optimum concentration of cysteine, NH₄NO_3, and yeast extract have produced 21.33 g/L biobutanol which is a 37.7% improvement from the non-optimized medium. The findings show that PKC hydrolysate with the addition of optimal concentrations of the three types of medium namely, cysteine (0.15 g/L), NH₄NO₃ (0.50 g/L), and yeast extract (1.5 g/L) during ABE fermentation, yielded a maximum biobutanol concentration of 21.33 g/L. Therefore, the results of this study provide good indications for promoting PKC hydrolysate as a new source of novel substrates with great potential in producing high biobutanol through ABE fermentation by C. saccharoperbutylacetonicum N1-4.

The Teratogenic Effect of Dimefluthrin-Based Mosquito Coils on Pregnant Mice (Mus musculus L.)

2024-03-31T04:25:50+00:00

Dimefluthrin, a synthetic pyrethroid insecticide, claims to be safe and harmless to mammals. However, the potential risk of mosquito coils containing dimefluthrin to pregnant mice remains uncertain. This study aimed to examine the teratogenic effect of dimefluthrin when inhaled by pregnant mice at different stages of gestation. The study used mosquito coils with 0.031% dimefluthrin as the active ingredient and was exposed to pregnant mice at various pregnancy stages. The results revealed that mosquito coils with dimefluthrin had teratogenic effects, reducing the number of live fetuses and increasing the number of dead fetuses, especially from the seventh to the eighteenth day of pregnancy. Additionally, there was a decrease in fetal weight, length, and volume, particularly during the seventh to eighth day of gestation. Hemorrhages were observed as fetal abnormalities and were highest three hr after exposure every day during pregnancy. The conclusion of this research is pregnant mice exposed to mosquito coil smoke containing dimefluthrin experienced a decrease in the number of live fetuses and an increase in fetal mortality. While there was no significant impact on reabsorption, the fetuses showed reduced weight, and size, and an increased incidence of hemorrhages when exposed for three hr daily during pregnancy.

Nodulation and Yields of Soybean (Glycine max L. Merrill) Varieties at Varying Phosphorus Fertilizer Rates in Lafia, Nigeria

2024-03-31T04:24:54+00:00

Soybean production in Lafia, southern Guinea savanna zone of Nigeria, is impacted by soil phosphorus deficiency, affecting nodulation, nitrogen fixation, and overall crop productivity. Field experiments were conducted in 2018 and 2019 cropping seasons with different phosphorus fertilizer rates (0, 13, 26 & 39 Kg P₂O₅ ha^-1) and six improved soybean varieties (TGX 1985-10F, TGX 1987-10F, TGX 1448-2E, TGX 1987-62F, TGX 1989-19F & TGX 1835-10E) to determine the effects of phosphorus fertilizer rates on nodulation and yields of soybean varieties. The results showed significant variation in soybean nodulation and yields when different phosphorus fertilizer rates were used. Among the six improved soybean varieties tested, TGX 1989-19F and TGX 1987-62F varieties performed best with 39 kg P₂O₅ ha^-1. The results also show that plots that received a 39 kg P₂O₅ ha^-1 produced the highest nodule number (26.3 & 28.7) and nodule weight (203.5 & 221.2 mg/plant) significantly in 2018 and 2019, respectively, compared to those with lower phosphorus rates. The effect of phosphorus fertilizer rates on soybean yields was apparent, with the 39 kg ha^-1 phosphorus treatment yielding significantly higher yields than the lower phosphorus treatments. Notably, the TGX 1989-19F variety consistently outperformed the others, yielding the highest yield (1624.0 kg/ha). Based on the results, it is recommended that soybean farmers in the Lafia region consider increasing their phosphorus rates to 39 kg ha^-1 for improved nodulation and subsequent yield gains. The TGX 1989-19F variety, due to its exceptional response to this phosphorus level, could be prioritized for cultivation to maximize returns. However, further research and on-farm trials must validate these findings across multiple growing seasons and farm management practices.

Enhancement of Growth Performance and Body Coloration Through The Inclusion of Torch Ginger Powder in The Feed of Red Tilapia (Oreochromis sp.)

2024-03-31T04:25:45+00:00

Red tilapia (Oreochromis sp.) is a highly produced aquaculture fish among freshwater species. Coloration is an important factor in determining consumer preferences. Therefore, an 8-week experiment was conducted to enhance the growth performance and body coloration through the inclusion of torch ginger in the feed of red tilapia. Five experimental feeds were prepared from commercial feed (crude protein: 34%, crude lipid: 5%) containing torch ginger powder at 2.5, 5.0, 7.5, and 10% (T₁, T₂, T₃, & T₄) inclusion levels while feeding without torch ginger act as a control (T₀). Red tilapia (Initial body weight: 0.4±0.1g; Initial total length: 4.0±0.1cm) were distributed at stocking number 20 fish/tank into fiberglass tanks with a capacity of 80 L and triplicates for each treatment. The fish were fed with experimental feeds until satiation. The growth of fish was significantly higher (P<0.05) when the fish fed with T₁, T₂, and T₃compared to control treatment T₀. Moreover, the feed intake was significantly increased (P<0.05) when the torch ginger powder was added to the experimental feeds. In addition, the FCR was significantly better (P<0.05) when the fish fed on T₁, T_2, and T₃compared to T₀. The inclusion of torch ginger powder in the feed did not significantly affect (P<0.05) the body protein and lipids of the experimental fish. The increment of redness was significantly higher (P<0.05) when the fish fed with T₁, T₂, T_3, and T₄compared to T₀. However, it showed a declining trend of redness when the inclusion of torch ginger increased to 5.0% and above. Thus, the present study suggested that the inclusion of torch ginger powder improved the performance and enhanced the body coloration of juvenile red tilapia. However, a further increase of torch ginger powder by more than 2.5% did not help in the enhancement of the body coloration.

Metals Accumulation of Tropical Shrub Melastoma malabathricum L. (Melastomataceae) Populations and Their Relation To Soil Edaphic Factor

2024-03-31T04:25:12+00:00

Melastoma malabathricum L. (Melastomataceae) is a widely distributed tropical shrub that grows in Southeast Asia. Recent research found that M. malabathricum has a bioremediatory potential that can accumulate high concentrations of toxic metals such as Al, Pb, As, and Cr. Thus, this study aimed to investigate the metal hyperaccumulation in M. malabathricum from various populations and their relation to soil edaphic factors. We collected mature leaves and soils of M. malabathricum from 15 different populations in Negeri Sembilan, Selangor, and Pahang in Peninsular Malaysia. These 15 populations consist of lowland forests, dump sites, riparian, oil palm and rubber plantations, paddy fields, and mining sites. We found that M. malabathricum accumulated high concentrations of Al (3.45±1.58 to 8.697±1.61 mg g^-1) followed by Fe (1.02±0.02 to 1.07±0.04 mg g^-1), Pb (0.013±0.001 to 0.016±0.001 mg g^-1), As (0.008±0.005 to 0.23±0.004 mg g^-1), and Cr (0.005±0.0003 to 0.02±0.01 mg g^-1). The highest concentration of soil Al was 85.95±5.00 mg g^-1, Fe with 69.960±7.47mg g^-1, Pb with 0.192±0.03 mg g^-1, As with 0.156±0.06 mg g^-1 and Cr with 0.133±0.03 mg g^-1. We found no significant association between high foliar metal concentrations of the metals (Al, Pb, As & Cr) with the soil chemical properties but some soil metal elements were intercorrelated with foliar metal concentrations. Understanding the potential of M. malabathricum in accumulating high levels of metal elements, provides useful information for phytoremediation works. Further research is required to investigate the mechanism uptake and tolerance of heavy metals in M. malabathricum.

Comparisons on Growth Performance, Survivability, Organoleptic Qualities and Economic Feasibility of Asian Seabass (Lates calcarifer) Reared in Different Salinities

2024-03-31T04:25:32+00:00

Asian seabass, Lates calcarifer is among the most cultured aquaculture species in the Southeast Asian region due to its remarkable tolerance for a diverse environmental fluctuation. In aquaculture, salinity has a direct influence on many biological, physiological and market value of any cultured fish. This study investigated the impacts of different salinities (0, 15, & 30 ppt) on Asian seabass growth, body indices, feeding performance, organoleptic qualities, and production cost for 85 days. Ninety fish were reared in 700-liter tanks equipped with recirculation system with 10 fish each tank. They were fed with commercial marine feed. The findings revealed Asian seabass in 15 ppt attained significantly higher (p>0.05) body weight (470.40 ± 41.16 g), total length (31.51 ± 0.81 cm), total feed intake (309.28 ± 35.66 g/fish) and daily feed intake (3.64 ± 0.42 g/fish/day) compared to 30 ppt but remained insignificant with 0 ppt. Meanwhile, there was no significant difference (p<0.05) in terms of body weight gain, specific growth rate, body indices, and feed conversion ratio of Asian seabass when reared in different salinities. The organoleptic qualities showed that rearing Asian seabass in different salinities has no significant effect (p<0.05) on odour, appearance, texture, and flavour score. However, the overall acceptance score of Asian seabass reared in 30 ppt (3.53 ± 0.22) was significantly higher (p>0.05) compared to 15 ppt but remained insignificant with 0 ppt. Economically, Asian seabass cultured in 15 ppt yielded the most optimal conditions for profitable production. The findings conclude 15 ppt can promotes enhanced growth performance and profitability, while 0 ppt and 30 ppt can promote consumer acceptance positively.

Effect of Food Waste on The Growth Performance, Waste Reduction Efficiency and Nutritional Composition of Black Soldier Fly (Hermetia illucens (L.), Diptera: Stratiomyidae) Larvae

2024-03-31T04:25:36+00:00

The rate of solid waste generation, especially in Malaysia, has become one of the major concerns for environmental and public health issues. Food waste accounts for the highest percentage of solid waste that ends up in landfills. Due to the living nature of humans and their involvement in agricultural, industrial, and municipal activities, the disposal of food waste happens on a regular basis. Due to the absence of an incineration plant, these wastes are commonly sent into landfills which are considered to be the most cost-effective method for disposal. Nevertheless, consideration for an alternative disposal method such as composting shall not be ruled out entirely. One of the established methods for composting food waste is the utilization of the larvae of the Black Soldier Fly. A study was conducted to assess the growth and nutritional composition, waste reduction capacity and nutritional composition of Black Soldier Fly Larvae (BSFL) reared on food waste. We found that the larvae reared with the food waste and effective microorganism (EM), LFWEM (BSFL reared with a mixture of food waste and effective microorganisms), have a slightly better relative growth rate (2.66 ± 0.35 day^-1) compared to larvae reared with only food waste (2.44 ± 0.17 day^-1). The waste reduction index was higher in the LFWEM group (5.36 ± 0.18 g/day) compared to the control group, LFC (BSFL reared with chicken feed) (4.85 ± 0.03 g/day) and the LFW (BSFL reared with food waste) group (5.13 ± 0.17 g/day). The nutritional composition of the BSFL reared using food waste shows some potential as it surpasses some of the amount of essential amino acids including Arginine, Histidine, Threonine and Valine, found in the commercially available animal feeds. This finding serves as a baseline to propose potential replacements for animal protein by using BSFL reared with food waste.

Evaluation of Growth Performance and Morpho-Meristic Characteristics in The Progenies of Barbonymus gonionotus and Barbonymus schwanenfeldii

2024-03-31T04:25:00+00:00

Recognizing the potential benefits of combining the favorable traits of both species, this study was designed to evaluate the culture performance and morphometric variations of F1 hybrids derived from artificial reciprocal hybridization between Barbonymus schwanenfeldii and Barbonymus gonionotus. Four crosses were successfully produced, namely B. gonionotus ♀ × B. gonionotus ♂ (GG), B. gonionotus ♀ × B. schwanenfeldii ♂ (GS), B. schwanenfeldii ♀ × B. schwanenfeldii ♂ (SS) and B. schwanenfeldii ♀ × B. gonionotus ♂ (SG). Uniform-sized fingerlings of pure GG, hybrid GS, pure SS, and hybrid SG were stocked at a rate of 50 fingerlings per fiberglass 1-tonne tank. The fingerlings were fed a commercial tilapia pellet (Dinding Malaysia) with 35% crude protein, the feeding was done twice a day, at 9:00 and 16:00, with equal portions given at each feeding. After 8 weeks of culture, the mean weight gained by GG, GS, SS, and SG was 7.09 ± 0.06, 5.75 ± 0.15, 4.69 ± 0.21, and 5.60 ± 0.17 g, respectively. The growth performance of the hybrid GS 5.75 ± 0.15 was significantly higher compared to the slow-growing SS (4.69 ± 0.21) but lower than the value recorded in GG (7.09 ± 0.06) under identical rearing conditions. A similar trend was observed in the final weight and specific growth rate (SGR) (%/day). In terms of FCR value, hybrid GS had the best value (1.10 ± 0.10) compared to hybrid SG (1.31 ± 0.13) or pure species (1.29 ± 0.09, 1.39 ± 0.13). Reciprocal hybrids showed intermediate morphometric traits between the two species; The reciprocal hybrids displayed intermediate morphometric traits that fell between the two parental species. The results of the discriminant function analysis confirmed that there were significant differences in the characters of all four species.

Foraging Behaviour of Three Shorebird Species on Coastal Mudflats of Southwestern Sarawak

2024-03-31T04:25:41+00:00

Many shorebirds are long-distance migrants and they congregate on intertidal mudflats for feeding throughout their non-breeding season. Despite being one of the key staging sites for migratory shorebirds, data on shorebirds foraging ecology in Sarawak is insufficient for the understanding of the interaction between shorebirds and their behaviour. This study aimed to determine the foraging behaviour of Whimbrel (Numenius phaeopus), Bar-tailed Godwit (Limosa lapponica) and Terek Sandpiper (Xenus cinereus) at Asajaya and Buntal mudflats. Data collection of this study was conducted at low tide, during two non-breeding seasons with a total of 12 months of sampling. Focal observations were conducted within a 50 m × 50 m quadrat. A total of 8 exclusive foraging techniques were observed for the three shorebird species, including: pecking, probing, picking, stabbing, snapping, submerging, sweeping and ingesting. Terek Sandpiper displayed all the exclusive foraging behaviours, whereas Whimbrel and Bar-tailed Godwit showed 7 and 5 behaviours, respectively. The three shorebirds also displayed non-exclusive foraging behaviours such as walking, preening and defecating. Spearman correlation test indicates a positive correlation between the foraging behaviours performed among three shorebird species. All three shorebird species adopted similar mixed foraging strategies comprising pecking and probing, with an exception on supplementary behaviours observed in Whimbrel and Terek Sandpiper. Principal Component Analysis (PCA) analysis showed a strong correlation between picking and ingesting behaviours, suggesting a high chance of foraging success with the presence of picking behaviour. The outcome of this study is crucial in understanding how shorebirds maximise their behavioural performance when foraging as well as to assist in formulating better conservation strategies for targeted migratory shorebird species and coastal mudflats.

An Updated Review of Ethnobotany, Ethnopharmacology, Phytochemistry and Pharmacological Activities of Orthosiphon stamineus Benth

2024-03-31T04:25:21+00:00

There are a myriad of potential medicinal plants worldwide. Researchers have found some, while others are still unexplored. Orthosiphon stamineus Benth. (family: Lamiaceae), commonly known as the cat's whiskers plant, is a well-known herbal plant with many medicinal uses. All the parts of O. stamineus, such as the leaves, stems, flowers, and seeds, have their uses. More than 140 pure compounds were identified and isolated from different extracts of O. stamineus, particularly leaf extracts and stem oils. Flavonoids are the most abundant phytoconstituents found in O. stamineus leaf extract. Several pharmacological activities have been studied and validated using extracts as well as pure compounds. Multiple phytoconstituents attributed to these pharmacological activities such as diuretics, antihyperglycemic, antioxidant, hepatoprotective, antiepileptic, etc., have been discovered. Considering the purported benefits of O. stamineus, the present review critically evaluates and discusses the pharmacognosy, taxonomy, ethnobotany, pharmacological activities, and phytochemistry of O. stamineus and provides updated information.
