is a rapidly growing thermotolerant yeast that secretes a variety of lytic enzymes, utilizes different sugars, and produces ethanol. The probiotic potential of this yeast has not been well explored. To evaluate its probiotic potential, the yeast strain DMKU3-1042 was analyzed using next-generation sequencing technology. Analysis of the genomes showed that the yeast isolates had a GC content of 40.10-40.59%. The isolates had many genes related to glycerol and mannose metabolism, as well as genes for acetoin and butanediol metabolism, acetolactate synthase subunits, and lactic acid fermentation. The strain isolates were also found to possess genes for the synthesis of different vitamins and Coenzyme A. Genes related to heat and hyperosmotic shock tolerance, as well as protection against reactive oxygen species were also found. Additionally, the isolates contained genes for the synthesis of lysine, threonine, methionine, and cysteine, as well as genes with anticoagulation and anti-inflammatory properties. Based on our analysis, we concluded that the strain DMKU3-1042 possesses probiotic properties that make it suitable for use in food and feed supplementation.
是一种快速生长的耐热酵母,能分泌多种裂解酶,利用不同糖类并产生乙醇。这种酵母的益生菌潜力尚未得到充分探索。为评估其益生菌潜力,使用下一代测序技术对酵母菌株DMKU3 - 1042进行了分析。基因组分析表明,酵母分离株的GC含量为40.10 - 40.59%。这些分离株有许多与甘油和甘露糖代谢相关的基因,以及与乙偶姻和丁二醇代谢、乙酰乳酸合酶亚基和乳酸发酵相关的基因。还发现菌株分离株拥有合成不同维生素和辅酶A的基因。也发现了与耐热和耐高渗休克以及抵御活性氧相关的基因。此外,分离株包含合成赖氨酸、苏氨酸、蛋氨酸和半胱氨酸的基因,以及具有抗凝和抗炎特性的基因。基于我们的分析,我们得出结论,菌株DMKU3 - 1042具有益生菌特性,使其适合用于食品和饲料补充。
