Kefir is a natural probiotic drink traditionally produced by milk fermentation using kefir grains. Kefir grains are composed of a complex population of bacteria and yeasts embedded in a polysaccharide-protein matrix. The geographic origin of kefir grains may largely influence their microbial composition and the associated kefir drink properties. Although the detailed bacterial composition of kefir grains from several geographic regions has been reported, to date, analogous data about the microbiome of Greek kefir are lacking. Hence, the aim of this study is to investigate the structure and the diversity of the bacterial community of Greek kefir grains.

来自两个地理区域的希腊开菲尔谷物微生物群的高通量、基于序列的分析。

开菲尔是一种天然益生菌饮料，传统上使用开菲尔谷物通过牛奶发酵生产。开菲尔谷物由嵌入多糖-蛋白质基质中的复杂细菌和酵母群组成。开菲尔谷物的地理来源可能在很大程度上影响其微生物组成和相关的开菲尔饮料特性。尽管已经报道了来自几个地理区域的开菲尔谷物的详细细菌组成，但迄今为止，缺乏关于希腊开菲尔微生物组的类似数据。因此，本研究的目的是研究希腊开菲尔谷物细菌群落的结构和多样性。
