diversity of spoilage fungi associated with various french dairy products.	yeasts and molds are responsible for dairy product spoilage, resulting in significant food waste and economic losses. yet, few studies have investigated the diversity of spoilage fungi encountered in dairy products. in the present study, 175 isolates corresponding to 105 from various spoiled dairy products and 70 originating from dairy production environments, were identified using sequencing of the its region, the partial β-tubulin, calmodulin and/or efα genes, and the d1-d2 domain of the 26s r ...	2017	27794247
engineering a wild-type diploid saccharomyces cerevisiae strain for second-generation bioethanol production.	the cost-effective production of second-generation bioethanol, which is made from lignocellulosic materials, has to face the following two problems: co-fermenting xylose with glucose and enhancing the strain's tolerance to lignocellulosic inhibitors. based on our previous study, the wild-type diploid saccharomyces cerevisiae strain bsif with robustness and good xylose metabolism genetic background was used as a chassis for constructing efficient xylose-fermenting industrial strains. the performa ...	2016	27942436
biocatalytic reduction of hmf to 2,5-bis(hydroxymethyl)furan by hmf-tolerant whole cells.	catalytic upgrading of 5-hydroxymethylfurfural (hmf), an important biobased platform chemical for high-value products, is currently of great interest. in this work, a new highly hmftolerant yeast strain-meyerozyma guilliermondii sc1103 was isolated, and biocatalytic reduction of hmf to 2,5-bis(hydroxymethyl)furan (bhmf) using its resting cells was reported. cosubstrates exerted a significant effect on the catalytic activity and selectivity of microbial cells as well as their hmf-tolerant levels ...	2017	27966286
lsp1, a responsive protein from meyerozyma guilliermondii, elicits defence response and improves glycyrrhizic acid biosynthesis in glycyrrhiza uralensis fisch adventitious roots.	this research explored the effects of protein and polysaccharide in meyerozyma guilliermondii on active compounds in glycyrrhiza uralensis fisch adventitious roots. in this study, a responsive protein lsp1 was purified from the meyerozyma guilliermondii since the excellent induction. the contents of total flavonoids (3.46 mg · g(-1) ), glycyrrhizic acid (0.41 mg · g(-1) ), glycyrrhetinic acid (0.41 mg · g(-1) ), and polysaccharide (94.49 mg · g(-1) ) in adventitious root peaked at lsp1 group, wh ...	2017	28105652
nitrile-hydrolyzing enzyme from meyerozyma guilliermondii and its potential in biosynthesis of 3-hydroxypropionic acid.	3-hydroxypropionic acid (3-hp) is an important platform chemical in organic synthesis. traditionally, 3-hp was produced by chemical methods and fermentation process. in this work, a novel enzymatic method was developed for green synthesis of 3-hp. a yeast strain harboring nitrile-hydrolyzing enzyme was newly isolated from environmental samples using 3-hydroxypropionitrile (3-hpn) as the sole nitrogen source. it was identified to be meyerozyma guilliermondii cgmcc12935 by sequencing of the 18s ri ...	2017	28285455
how native yeasts may influence the chemical profile of the brazilian spirit, cachaça?	cachaça is the typical brazilian spirit, obtained by distillation of fermented sugarcane must, whose production is closely related to regional heritage and geographical traits. in this work, we investigate the influence of different autochthonous yeast species, in comparison to other commercial strains, on the chemical profile of cachaça. fermentations were performed with four different wild species, a mixed starter culture with native yeasts, and two commercial strains. procedures were carried ...	2017	28290322
metagenomics analysis of microbial communities associated with a traditional rice wine starter culture (xaj-pitha) of assam, india.	this is the first report on the microbial diversity of xaj-pitha, a rice wine fermentation starter culture through a metagenomics approach involving illumine-based whole genome shotgun (wgs) sequencing method. metagenomic dna was extracted from rice wine starter culture concocted by ahom community of assam and analyzed using a miseq(®) system. a total of 2,78,231 contigs, with an average read length of 640.13 bp, were obtained. data obtained from the use of several taxonomic profiling tools were ...	2016	28330225
