The differences of interaction between interphase microbial communities were evaluated caused by two kinds of , including conventional (CDQ) and fortified (FDQ). The community diversity, functional genera and metabolites in pit mud (PM) and (ZP) were investigated by polyphasic detecting approaches. FDQ evolved the core microbial community fitting brewing faster than CDQ. Compared with CPM, the abundance of , , and in FPM were 1.54, 14.75, and 1.68 times, while that of , , , and were 2.13, 1.85, 6.35, and 3.36 times, respectively. Furthermore, the content of key flavor components was increased in ZP using FDQ. These results suggested the interaction between interphase microbial communities in various phases of fermentation niches was significant influenced by . It can not only enhance the key volatiles in ZP but also evolve the community to fit fermentation by introducing functional genera to .

评估了两种大曲(包括传统大曲(CDQ)和强化大曲(FDQ))引起的相间微生物群落相互作用的差异。采用多相检测方法研究了窖泥(PM)和糟醅(ZP)中的群落多样性、功能菌属和代谢产物。FDQ比CDQ更快地进化出适合浓香型白酒酿造的核心微生物群落。与CPM相比,FPM中己酸菌、丁酸菌和醋酸菌的丰度分别是其1.54、14.75和1.68倍,而乳酸菌、芽孢杆菌、酵母菌和霉菌的丰度分别是其2.13、1.85、6.35和3.36倍。此外,使用FDQ时ZP中关键风味成分的含量增加。这些结果表明,浓香型白酒发酵生态位各阶段相间微生物群落之间的相互作用受大曲显著影响。它不仅可以提高ZP中的关键挥发性成分,还可以通过向糟醅引入功能菌属来使群落进化以适应浓香型白酒发酵。
