Fermented foods from jalebi to dosa are common across India. Scientists are now focusing on them as fermented foods are not just a part of food culture but they also harbour microbial diversity. A study of 'starters’ that are used to prepare ethnic fermented foods in Sikkim and Meghalaya has revealed that they have rich microbial diversities. The novel study was undertaken to find out the type of bacteria and fungi present in two traditionally prepared ‘starters’-marcha and thiat-which are used to ferment a variety of starchy substances to produce a sweet alcoholic beverage popular in the two north-eastern states. The traditional practice of using marcha and thiat starters in the process of fermentation is an integral part of socio-cultural heritage of Sikkim and Meghalaya respectively. This technique also helps in keeping alive important locally-found bacteria and fungi which could otherwise disappear over time.Marcha and thiat are traditionally-prepared starters similar to s...
