Comprehensive analysis for the bioturbation effect of space mutation and biofortification on strong-flavor Daqu by high-throughput sequencing, volatile analysis and metabolomics.

Abstract excerpt

Daqu, an indispensable starter, significantly affects the quality and yield of Chinese baijiu. To explore the bioturbation effect of space mutation and biofortification on strong-flavor Daqu, the microbial community, physicochemical properties and overall metabolic profile were investigated. Lactobacillus and Aspergillus were significantly reduced after bioturbation, while seven genera (e.g., Bacillus and Pichia)...
