Artificial pit mud (APM) is a fermented product that uses fresh soil as the primary material. In the Chinese Baijiu brewing industry, APM has been widely used since the 1960s to construct fermentation cellars for production of high quality strong-flavor baijiu (SFB). However, despite its importance, our knowledge of the molecular basis of APM microbial dynamics and associated functional variation during SFB brewing is limited, and the role of this variability in high quality SFB production remains poorly understood. In this study, APM samples were removed from new cellars at the end of the first to the fourth SFB brewing batch and subjected to multi omics analysis to characterize APM prokaryotic taxonomic and functional dynamics. The results provide insight into global APM prokaryotic dynamics and their role in SFB production, which will be helpful for further optimization of APM culture technique and improvement of SFB quality.
