Extensive profiling of the diversity of yeasts and mycelial molds in various traditionally prepared dry starters collected from different places of North East India have been reported earlier (Tamang et al., 1988; Tamang and Sarkar, 1995; Tsuyoshi et al., 2005; Jeyaram et al., 2008, 2011; Bora et al., 2016; Sha et al., 2017, 2018, 2019).

However, research and studies in the field of microbiology has been concentrated on bacteria, archaea, fungi, protozoa, and viruses (although some people consider viruses to be non-living [6], as they cannot survive/multiply on their own).
