Chinese soy-based microbiome and associated microbial risks: a metagenomic investigation.

ABSTRACT: Fermented foods are a longstanding part of the Chinese diet and have been recognized for promoting gut microbial diversity. However, their microbial composition remains poorly defined, raising concerns about potential exposure to pathogens and antibiotic resistance genes (ARGs). Using shotgun metagenomics, we examined microbiota of 93 representative samples spanning three major categories of traditional Chinese fermented soybean products. We identified distinct microbial and functional profiles across food types, with antagonism between beneficial taxa (Bacillales and Lactobacillales) and harmful Enterobacterales. Comparative analysis with public Chinese gut microbiomes revealed species- and strain-sharing between fermented foods and human gut microbiota, identifying certain products as so
