Pit mud metagenome

The degradation of pit mud in fermentation cellars seriously compromises the quality of Chinese strong-flavor Baijiu (SFB). In this study, a biological mixture produced from brewing wastes was used to restore degraded pit mud (DPM). The prokaryotic communities in the restoration and subsequent brewing period were investigated by metagenomics.The results demonstrate that brewing wastes can be reused to restore DPM. Generally, these findings could aid the development of new sustainable strategies to produce high-quality SFB.
