Multi-Metaomics Unveils the Development Process of Microbial Communities During the Fermentation of Baobaoqu

In order to understand the dynamic interaction process among species, enzymes, and metabolites during the fermentation process of Baobaoqu, which is a representative Daqu starter for Chinese baijiu, the intimate connection between the progression of microbial communities and the diversities and activities of enzymes was examined by metagenomics, metatranscriptomics and metaproteomics. It was found that while 5211 species of mi- croorganisms were detected by metagenomics, only 1774 active...
