Research ArticleOpen accessIn the abstractAntifungal Activity of Jatropha Curcas Linn on Candida Albicans and Candida Tropicalis Associated with Neonatal and Infantile Infections in Yola, NigeriaJames Hamuel Doughari, Martha AbrahamOne hundred and eighty (180) stool samples collected of neonates and infants from three selected health facilities in Yola, Adamawa State Nigeria. The samples were subjected to both microscopic, biochemical test and cultural identification. Bromocresol green agar and Germ tube test was used to identify Candida species. Culture of the stool samples on SDA yielded 32 yeast cells with Candida … …American Journal of Agricultural and Biological Sciences, Vol. 16, Issue 1 · 7 Sep 2021 · 7,533 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Nitrogen Source on the Lipid Accumulation in Phaeodactylum TricornutumXiaojie Ren, Qi Yan, Song Li et al.Nitrogen source has an important influence on the growth and lipid synthesis of Phaeodactylum tricornutum. It affects lipid accumulation through global metabolic regulation. However, little research has been done on the correlation between other metabolites and lipid metabolism during the synthesis of Phaeodactylum tricornutum. In this study, we studied the effect of different nitrogen sources on lipid and other major … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 27 Jul 2020 · 6,913 accessesView PDFCite
Research ArticleOpen accessIn the abstractProduction of Selenium-Enriched Yeast (Kluyveromyces marxianus) Biomass in a whey-based Culture MediumNicolás Gurdo, Mario Calafat, Diego Gabriel Noseda, Isabel GigliTwo important aspects of agriculture intensification are the reduction in the concentration of specific soil minerals that affects livestock production and the increase of agricultural by-products, which produce environmental pollution. In this regard, whey - a cheese by-product-often is considered a wasted-product. Due to its lactose concentration, (4.5%), when whey is discarded without treatment generates a high Biological Oxygen Demand … …American Journal of Biochemistry and Biotechnology, Vol. 14, Issue 2 · 28 Jun 2018 · 11,375 accessesView PDFCite
Research ArticleOpen accessIn the abstractCocoa-Butter-Equivalent Production from Yarrowia lipolytica by Optimization of Fermentation TechnologyLina Zhao, Bo Li, Dan Xiong et al.In order to obtain the optimal control point for single-cell lipid production with fatty acid profile similar to cocoa butter, this study explored the effects of carbon source, nitrogen source, temperature, sterculic acid methyl ester, cobalt on cell growth and lipid accumulation of Yarrowia lipolytica. Glycerol and ammonium tartrate-yeast extract were chosen as carbon source and nitrogen source for production … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 4 · 29 Dec 2016 · 9,285 accessesView PDFCite
Research ArticleOpen accessIn the abstractChemical Mutagenesis for Improvement of Production of a Biologically Active Extracellular Polymeric Substance by Halomonas xianhensis SUR308Jhuma Biswas, Amal K. PaulA moderately halophilic bacterium, Halomonas xianhensis SUR308 (Genbank Accession No. KJ933394) isolated from solar saltern of Surala, Odisha, India was found to produce significant amount of a biologically active extracellular polymeric substances (EPS). Under optimized cultural conditions, the strain was able to produce 7.05 g L-1 of EPS after 8 days of incubation under shake culture. To enhance the EPS … …Current Research in Microbiology, Vol. 7, Issue 1 · 1 Apr 2016 · 15,918 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Cultural Conditions for Production of Exopolysaccaride by Halomonas marina HMA 103 under Batch-CultureArundhati Pal, Amrita Biswas, Sriya Chatterjee, A. K. PaulA moderately halophilic bacterium, Halomonas marina HMA 103 (MTCC 8968) accumulating intracellular polyesters also produced significant amount of exopolysaccharides (EPS) under batch-culture. Production of EPS by the bacterium was more or less parallel with the growth in modified basal synthetic medium. During growth, it produced 0.46 g/L of EPS after 50 h of incubation and was accompanied by the complete … …Current Research in Microbiology, Vol. 6, Issue 2 · 27 Jul 2015 · 7,932 accessesView PDFCite
Research ArticleOpen accessIn the abstractIsolation and Characterization of Organophosphate Pesticides Degrading Bacteria from Contaminated Agricultural SoilSoni Yadav, Sitansu Kumar Verma, Hotam Singh ChaudharyThe soil sample was collected from Agriculture University Gwalior, Madhya Pradesh, India which is having a history of repeated pesticide application. Bacterium capable of degrading Malathion and Dichlorvos were isolated and identify as Staphylococcus sp. Micrococcus sp. Entrobacte sp. Bordetella sp. Pseudomonas sp. and Klebsella sp. The growth of all six pesticide degrading isolates was assessed in Mineral Salt Medium … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 30 Jun 2015 · 7,589 accessesView PDFCite
Research ArticleOpen accessIn the abstractScreening of Yeast Strains for Pectinolytic Activity: Effects of Different Carbon and Nitrogen Sources in Submerged FermentationsMustafa Oskay, Hüsniye Tansel YalçinTwenty yeast strains were screened for pectinolytic activity, among the strains, only nine were positive for pectinase production. The best strain was Kluyveromyces marxianus NRRL-Y-1109 which gave high quantities of pectinase activity, by submerged fermentation. Different parameters such as incubation time, pH (3.5-7), temperature (20-45°C), nitrogen and carbon source, were optimized. The optimal incubation time, temperature and pH for pectinase … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 22 Jun 2015 · 7,812 accessesView PDFCite
EditorialOpen accessIn the abstractRe-Paving the Road Built by Chemistry: A Challenge to Biochemistry and BiotechnologyAlberto A. IglesiasBiochemistry’s birth can be placed at the end of the nineteenth century, when Eduard Buchner made a clever interpretation of experimental observations on the generation of gas bubbles after addition (the original purpose was preservation) of sucrose to a yeast crude extract (Lagerkvist, 2005). Intelligently, Buchner concluded that the disaccharide had been fermented by broken cells’ suspension to produce CO2, … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 26 Jan 2015 · 7,461 accessesView PDFCite
Research ArticleOpen accessIn the abstractIMPROVED PREDICTION FOR MEDIUM OPTIMIZATION USING FACTORIAL SCREENING FOR DOCOSAHEXAENOIC ACID PRODUCTION BY SCHIZOCHYTRIUM SP. SW1Vidyah Manikan, Mohd Sahaid Kalil, Mohd Hafez Mohd Isa, Aidil Abdul HamidDocosa Hexaenoic Acid (DHA) is an essential fatty acid that plays major role in human health. It is typically extracted from fatty fish and this puts pressure on global fish stock. DHA obtained from fish is also prone to contamination. Schizochytrium is a potential alternative source, having the ability of accumulating considerable amounts of DHA. Modification of medium components and … …American Journal of Applied Sciences, Vol. 11, Issue 3 · 15 Jan 2014 · 7,837 accessesView PDFCite
