Kimchi is manufactured using salted vegetables and various seasonings, including garlic, scallion, and jeotgal (fermented seafood). However, similar to vegan diets, Korean temple food does not contain animal products (meat- and seafood-free) and is restricted to five pungent herbs: garlic, scallion, leek, onions, and chives. In this study, we investigated the fermentation characteristics of 25 kimchi samples from traditional Korean temples or commercial sources using Illumina MiSeq sequencing. The initial pH of the kimchi samples ranged from 5.05 to 5.95 and the bacterial diversity-index showed a significantly high value in temple-style kimchi. Moreover, differences in microbial community were significantly reflected in kimchi types using non-metric multidimensional scaling plots and analysis of similarity. Additionally, the distribution patterns of the core bacterial genera differed according to kimchi type, especially during early phases of fermentation. These findings offer novel insights into the microbial ecology and quality characteristics of kimchi lacking vital ingredients, which are generally reported based on the origin of the microorganisms.
