The results showed that among the six Daqu samples, the bacteria mainly included Firmicutes, Actinobacteriota, and Proteobacteria, of which Proteobacteria was the most dominant. The primary fungus was Ascomycota. At the genus level, the primary bacterial groups were Lactobacillus, Weissella, Bacillus, Delftia, Achromobacter, Saccharopolyspora, Thermoactinomyces, Scopulibacillus, Pseudomonas, and Stenotrophomonas. The main fungal groups in the Daqu were Wick3 BiotechMicrobial composition and dynamic succession during the Daqu production process of Northern Jiang-flavored liquor in China.PMC8053632BME-202001FRF-TP-18-012A1; FRF-BR-19-003BShen LYang WLiu YZhang YJiang QWang ZSun JWu XXu YfalseMicrobial composition and dynamic succession during the Daqu production process of Northern Jiang-flavored liquor in China.The microbial community structure and succession regularity of six key periods during high-temperature Daqu production were revealed using high-throughput sequencing to explore the factors affecting the flavor formation of Northern Jiang-flavored Baijiu technology.
