Progress on the application of omics technologies in Baijiu brewing microorganism

Chinese Baijiu is one of the famous distilled spirits with unique flavor in the world. The formation of the unique flavor is usually due to the microbial community structure, gene expression, metabolic pathway, enzyme activity and coordination of metabolites in the process of Baijiu brewing. The rapid development of omics methods provides technical support for the analysis of microbial diversity and function and their influence on Baijiu flavor. Therefore, a systematic overview on the application progress of genomics, transcriptomics, proteomics and metabolomics technologies in research on brewing microorganisms was provided. Furthermore, future research perspectives were presented to provide ideas for theoretical research and production practice of Baijiu brewing.
