One approach towards maintaining healthy microbiota in the human gastrointestinal tract is through the consumption of probiotics. Until now, the majority of probiotic research has focused on probiotic bacteria, but over the last few years more and more studies have demonstrated the probiotic properties of yeast, and also of species besides the well-studied var. . Probiotic strains have to present the ability to survive in harsh conditions of the host body, like the digestive tract. Must fermentation might be an example of a similar harsh environment. In the presented study, we examined the probiotic potential of 44 yeast strains isolated from Polish wines. The tested isolates belonged to six species: and . The tested strains were subjected to an assessment of probiotic properties, their safety and their other properties, such as enzymatic activity or antioxidant properties, in order to assess their potential usefulness as probiotic yeast candidates. Within the most promising strains were representatives of three species: , and . strains 15 and 16, as well as strain 37, showed, among other features, survivability in gastrointestinal tract conditions exceeding 100%, high hydrophobicity and autoaggregation, had no hemolytic activity and did not produce biogenic amines. The obtained results show that Polish wines might be a source of potential probiotic yeast candidates with perspectives for further research.
维持人类胃肠道健康微生物群的一种方法是食用益生菌。到目前为止，大多数益生菌研究都集中在益生菌细菌上，但在过去几年中，越来越多的研究证明了酵母以及除了经过充分研究的变种之外的其他物种的益生菌特性。益生菌菌株必须具备在宿主体内恶劣条件下生存的能力，比如消化道。必须发酵可能就是类似恶劣环境的一个例子。在本研究中，我们检测了从波兰葡萄酒中分离出的44株酵母菌株的益生菌潜力。测试的分离株属于六个物种：[此处未给出具体物种名称]。为了评估它们作为益生菌酵母候选菌株的潜在用途，对测试菌株进行了益生菌特性、安全性以及其他特性（如酶活性或抗氧化特性）的评估。在最有前景的菌株中，有三个物种的代表：[此处未给出具体物种名称]。菌株15和16以及[此处未给出具体物种名称]菌株37，除其他特征外，在胃肠道条件下的存活率超过100%，具有高疏水性和自聚集性，无溶血活性且不产生生物胺。所得结果表明，波兰葡萄酒可能是潜在益生菌酵母候选菌株的来源，具有进一步研究的前景。
