Significance and Impact of the Study: This study revealed the diversity of yeasts in some traditional kefir samples from Iran. Kluyveromyces marxianus was the dominant yeast species followed by Saccharomyces cerevisiae, P. fermentans and P. kudriavzevii. Three isolates of S. cerevisiae and one isolate of P. fermentans were exhibited high abilities of adherence to different solvents and auto-aggregation and acceptable adhesion to the epithelial intestine-derived cells but no antimicrobial activity against investigated pathogens. Although further studies on their health benefits and in vivo trials are required, these findings suggest that the yeast isolates can be considered as possible probiotic candidates for the development of novel functional foods.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
