Recent advances and perspectives in study of microbiome in Chinese Jiuqu starter

Abstract:

Jiuqu starter serves as the saccharifying and fermenting agent for Chinese baijiu production, and plays an important role in determing the quality and flavor characteristics of baijiu. The quality of Jiuqu is associated with the compositions of its microbial communities and enzymes. Studies on Jiuqu microbiome would reveal rich scientific connotation and have extensive application prospects. Jiuqu microbiome presents a high microbial diversity and has abundant enzymes. Meanwhile, Jiuqu microbiome is correlated with the manufacturing environmental factors. Based on profiles of Jiuqu microbiome, researchers try to enhance functional microbes to develop intensified Jiuqu or develop pure culture, to improve the quality and brewing function of Jiuqu. In this review, we summarized advances in traditional Jiuqu microbiome features, Jiuqu microbiome theory development and application, and research direction of Jiuqu microbiome in recent years.
