Research ArticleOpen accessEvery word in the titleIsolation and Screening of Wine Yeasts from Grapes in Yalu River Valley China for Fermentation PerformanceXiaochun Yu, Jing Xu, Yuan Peng Li, Xian Peng LiIn order to further explore the diversity of yeast in grape brewing in Yalu River Valley, northern China and to better exploit and utilize the yeast resources in a grape producing area, we investigated soil, grape residue after juice extraction and naturally fermented grape juice samples collected from grape plantations in the Yalu River Valley in this study. Twelve yeast … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 25 Sep 2021 · 6,330 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleYeast Immobilization on Peanut Hulls for Potential Application in Beer FermentationWaldir D. Estela-Escalante, Sergio Rosales-Mendoza, Mario Moscosa-SantillánThe potential of using peanut hulls as support material for immobilization of yeast cells during beer fermentation was evaluated. After treatment of peanut hulls with 0.5% (w/v) NaOH, FTIR analysis revealed an important change on its chemical composition. For instance, the proportion of lignin decreased and as a result the adsorption of yeast cells onto the support material during fermentation … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 22 Jul 2019 · 8,375 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleProduction, Extraction and Characterization of Lipases from the Antarctic Yeast Guehomyces pullulansLuis Lascano-Demera, Patricia Portero Barahona, Enrique Javier Carvajal BarrigaThe production of extracellular lipases from the Antarctic yeast Guehomyces pullulans is induced using an olive oil medium as an inductor substrate and a first characterization of its enzyme, using the protein extract obtained from the medium, is described. For this, the effect of pH and temperature on the lipase activity are evaluated and the enzyme kinetic for the lipase … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 11 Apr 2019 · 10,020 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThe Visceral Organ, Gastrointestinal Tract and Blood Characteristics in Pegagan Ducks Fed Ration Fermented by Tape Yeast with Different Moisture ContentFitra Yosi, Sofia Sandi, MiksusantiThe purpose of this study was to assess the effect of administration diet containing locally sourced materials fermented by tape yeast with different moisture content on the weight of the visceral organs, gastrointestinal tract and blood chemistry and profile of Pegagan ducks. As many as 200 Pegagan ducks aged 3 days were kept for 6 weeks in colony cages. This … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 3 · 19 Aug 2017 · 9,228 accessesView PDFCite
Research ArticleOpen accessEvery word 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 PDFCite
Research ArticleOpen accessEvery word in the titleEFFECT OF REPLACING CORN AND SOYBEAN MEAL WITH BREWERS RICE AND DRIED DISTILLERS BREWERS YEAST ON PERFORMANCE OF GROWING-FINISHING PIGSOndieki Gekara, Talesha Dokes, Renita MarshallThe objective of this study was to determine the effect of replacing corn and Soybean Meal (SBM) with Brewers Rice (BR) and Dried Distillers Brewers Yeast (DDBY), respectively, on ADG, G:F, Apparent Total Tract Digestibility (ATTD), fecal DM output and fecal loss of N and P of growing-finishing pigs. Sixty four Yorkshire x Duroc x Hampshire crosses (BW = 73±5.7 … …American Journal of Animal and Veterinary Sciences, Vol. 9, Issue 2 · 24 Apr 2014 · 7,193 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Dietary Yeasts Enriched with Cu, Fe and Mn on Digestibility of Main Nutrients and Absorption of Minerals by Growing PigsDaniel Korniewicz, Zbigniew Dobrzanski, Katarzyna Chojnacka et al.Yeasts Saccharomyces cerevisiae containing in 1 kg of dry product, separately 32.0 g Fe (Y-Fe), 23.0 g Cu (Y-Cu), 35.4 g Mn (Y-Mn), were used as the source of these microelements in complete diet for growing pigs. If considering livestock requirements, feed supplementation with this organic form of microelements, covered animals’ requirements in: Fe-27%, Cu-75%, Mn-30%. ZnO was the source … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,707 accessesView PDFCite
Review ArticleOpen accessEvery word in the titleComparative Study on Microbial Communities of Soil, Grape Must and Wine Fermentation of Cabernet Sauvignon Inoculated with three Commercial Yeast of Saccharomyces cerevisiaeRongbin Li, Xu Shi, Yaqiong Liu et al.This study examined the microbial diversity in soil, grape must and wine fermentation of Cabernet Sauvignon inoculated with three different starters (S01: Xinjiang Saccharomyces cerevisiae CEC01; SCA: Ningxia Saccharomyces cerevisiae CECA; S96: Saccharomyces cerevisiae AWRI 796) using a high-throughput sequencing technique. The results showed that 227 bacterial genera and 20 fungi genera were shared in all samples, consisting of Saccharomyces, … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 4 · 24 Dec 2021 · 5,997 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEffect of Autolyzed Yeast Supplementation on Productive Performance Meat Quality Visceral Organ and Cecum Bacteria of Broiler ChickensSirinapa Taechanan, Kanokporn Poungpong et al.We assessed the effects of dietary Autolyzed Yeast (AY; Saccharomyces cerevisiae) on the performance, meat quality, visceral organ weights, and cecum bacteria of broiler chickens. We utilized a total of 360 one-day-old male Ross308 chicks. We allocated the chicks to four different dietary treatments, each consisting of six duplicates. Each replica consisted of 15 chicks per pen. The study included … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 19 Sep 2024 · 5,086 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleApoptosis in Yeast is Modulated by Clove Leaf Extract and Eugenol Potentially by Interfering Caspase YCA1Septyani Amini, Rika Indri Astuti, Irmanida BatubaraApoptosis is a process of cell death important for preventing the development of diseases such as cancer, neurodegenerative disorders, autoimmune, and cardiovascular disease. Apoptosis is reported to be potentially induced by antioxidant compounds, including phytoextract. Thus in this study, we determined the potential of apoptotic modulation in yeast cells by clove extract, which was rich in eugenol.
