Bacterial community in pit mud of Yibin Baijiu in China by high throughput sequencing

Yibin Baijiu (YB) is a special Chinese strong-aroma baijiu (CSAB) origined in Yibin, a western city of China. YB is fermented in cellars lined with pit mud (PM), of which the microbiota affect the quality. In the study, 16S rRNA high throughput sequencing was used to demonstrate the bacterial community structure and diversity in PM of YB. Our study provided basic data for further elucidating diversity of microbiota in pit mud of YB and the potential mechanism of Baijiu production.
