Diversity of yeasts in Indian fermented foods and alcoholic beverages

Abstract

Ethnic Indian people have been domesticating beneficial microorganisms (bacteria, yeasts and moulds) by their wisdom of ethno-microbiological knowledge for production of flavoured and socio-culturally preferred fermented foods and alcoholic beverages for more than 8000 years. The purpose of this review is to collate the available literatures of diversity of Saccharomyces and non- Saccharomyces species associated with Indian fermented foods and alcoholic beverages. A colossal diversity of enzyme- and alcohol-producing yeasts under phylum Ascomycota has been reported from Indian fermented foods and alcoholic beverages. The distributions of yeast species show 13.5% of Saccharomyces cerevisiae and 86.5% of some non-Saccharomyces spp. in Indian fermented foods and alcoholic beverages, based on the reported literatures available till date. There is a research gap on prospect of yeasts research in India. Hence, we suggest that validation of traditional knowledge of domestication of functional yeasts needs to be studied to develop the functional genomics platforms for Saccharomyces and non-Saccharomyces spp. in Indian fermented foods and alcoholic beverages.

Probiotic yeasts: a developing reality?

“…Further possibilities are represented by developing specific fermentation processes using various probiotic yeast strains. This could lead to fermented foods designed to target certain health concerns, like gut inflammation or immune function [75][76][77]. Moreover, probiotic yeasts might offer advantages when it comes to delivering beneficial microbes to the gut.…”

Genetic diversity of non-Saccharomyces yeasts associated with spontaneous fermentation of Cabernet Sauvignon wines from Ningxia, China

“…In recent years, the regional flavor peculiarity of non -Saccharomyces strains has drawn widespread attention, and there are increasing demands for wine style diversification and local characteristics. Therefore, growing studies worldwide begin to focus on the development and utilization of wine-related non -Saccharomyces yeasts ( Binati et al, 2019 ; Zhao et al, 2021 ; Lai et al, 2022 ; Morata et al, 2022 ; Tamang and Lama, 2023 ).…”
