Research ArticleOpen accessPhrase in the titleScreening 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 PDF Cite

Research ArticleOpen accessPhrase in the titleTemperature Optimization for Bioethanol Production from Corn Cobs Using Mixed Yeast StrainsClarence S. Yah, Sunny E. Iyuke, Emmanuel I. Unuabonah et al.Problem statement: Dilute sulphuric acid and enzymatic hydrolysis methods were used for sugar extraction. Xylose and glucose sugars were obtained from corn cobs. Approach: Acid hydrolysis of corn cobs gave higher amount of sugars than enzymatic hydrolysis. Results: The results showed that optimal temperature and time for sugar fermentation were approximately 25°C and 50 h by two yeast strains (S. … …OnLine Journal of Biological Sciences, Vol. 10, Issue 2 · 30 Jun 2010 · 9,339 accessesView PDF Cite

Twelve yeast … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 25 Sep 2021 · 6,330 accessesView PDF Cite

Research ArticleOpen accessIn the abstractThe Effect of the Saccharomyces Boulardii Supplement in Combined Feed on the Health, Growth, and Fecal Microbiota of Growing CalvesDulat Zhalelov, Serkan Ozkaya, Mehmet Gündoğdu et al.The aim of this study was to study the effect of a specific strain of yeast, Saccharomyces cerevisiae boulardii T8-3C (SCB), on the growth, health, and bacterial profile of calves' feces. A total of 12 animals were included in the experiment on a commercial calf farm for a total of 90 days. The calves were fed hay and alfalfa twice … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 27 Nov 2025 · 2,309 accessesView PDF Cite

Research ArticleOpen accessIn the abstractChemical Composition and Antibacterial Activity of Subcritical CO2 Extract of Beta vulgaris L.Aidana Yerubay, Saule Akhmetova et al.The perpetual quest for novel antimicrobial agents is an ongoing endeavor within the scientific community. Contemporary investigations concerning members of the family Amaranthaceae, Beta vulgaris, have disclosed significant therapeutic properties in plants that were formerly exclusively employed as dietary resources. The roots and stems of red beets (Beta vulgaris L. var. conditiva) have been found to possess medicinal properties attributed … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 4 Jan 2024 · 4,970 accessesView PDF Cite

Research ArticleOpen accessIn the abstractTranscriptomic Analysis of the Erythritol High-Yielding Mutant Strain Yarrowia lipolytica Y44Xiaojie Ren, Heng Ban, Chao Huang et al.RNA-seq technique was used to analyze the transcriptomics of Yarrowia lipolytica control strain Po1g, an erythritol-producing natural isolate Yarrowia lipolytica Y 22 and an erythritol high-yielding mutant strain Y44 derived from Y 22. Functional annotation of genes and classification of metabolic pathways were carried out to identify Differentially Expressed Genes (DEGs). These DEGs were classified into related metabolic pathways to … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 20 Dec 2021 · 6,115 accessesView PDF Cite

Research NotesOpen accessIn the abstractScreening of Saccharomyces cerevisiae: A Strategy to Enhance Flavour of Jujube LiquorXiaolei Guan, Yaqiong Liu, Yao Lu et al.The main objective of this study was to isolate newly indigenous yeast strains from the fermentation of jujube liquor. 19 isolated yeast strains were obtained by spontaneous solid-state fermentation and flavour characteristics of the fermented jujube juice were also compared from above selected strains. 3 strains (JM-3, JM-13, JM-17) were screened out and identified as Saccharomyces cerevisiae (S. cerevisiae) by … …American Journal of Biochemistry and Biotechnology, Vol. 16, Issue 3 · 17 Jul 2020 · 6,626 accessesView PDF Cite

Research ArticleOpen accessIn the abstractBioconversion of Corn Steep Liquor to Biofertilizer by Symbiotic FermentationXiaojie Ren, Zhuangzhuang He, Huihui Peng et al.Corn Steep Liquor (CSL) is wastewater from corn starch industry. The huge amount generation made it as a serious environmental problem. But CSL is nutrient-rich with diverse amino acids and other trace elements. In this study, symbiotic biofertilizer was studied using CSL as main substrate. In this study, 9 industrial strains, which were recognized as high performance species in the … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 23 Dec 2021 · 6,613 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEthanol Production by Novel Proline Accumulating Pichia kudriavzevii Mutants Strains Tolerant to High Temperature and Ethanol StressesRika Indri Astuti, Sena Alifianti, Ratu Nabila Maisyitoh et al.Accumulation of osmoprotectant molecule, proline, has been reported to induce a stress tolerance phenotype in yeast cells. In this study, two ethanologenic isolates of yeast, Pichia kudriavzevii (R and T), both capable of using both five and six sugar compounds to produce ethanol, were mutated via ethyl methanesulfonate (EMS) treatment. Prolineaccumulating mutant strains were selected by using proline-analogue (L-azetidine-2-carboxylic acid). … …OnLine Journal of Biological Sciences, Vol. 18, Issue 3 · 11 Sep 2018 · 7,838 accessesView PDF Cite

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 PDF Cite
