Comparative analysis of metagenomics between high- and medium-temperature daqu, and microbial succession in Jiang-Nong Jianxiang Baijiu fermentation.

ABSTRACT:

Background

The mixture of high-temperature Daqu and medium-temperature Daqu can be used to produce Chinese Jiang-Nong Jianxiang Baijiu. This study used metagenomic sequencing and physicochemical analysis to investigate the microbial community and functionality of high-temperature Daqu and medium-temperature Daqu. In addition, exploring the changes of microbial communities during the Jiang-Nong Jianxiang Baijiu fermentation process.

Results

The results showed that Lichtheimia ramose and Saccharopolyspora rectivirgula were the significantly different species in high-temperature Daqu. However, Paecilomyces variotii, Aspergillus chevalieri, and Rasamsonia emersonii were the significantly different species in medium-temperature Daqu. The medium-temperature Daqu had higher sacchar
