Distinct bacterial community of a solid-state fermented Chinese traditional food huase sufu revealed by high-throughput sequencing.

UNLABELLED

Sufu is a common solid-state traditional fermented food made from soybean. Huase sufu is a typical type found in several provinces of China, especially in Hubei. However, little is known about the bacterial community. High-throughput sequencing technology revealed that the dominant taxa at phylum level were: Firmicutes, Proteobacteria and Bacteroides, and at the genus level were: , , , etc. Additionally, LEfSe revealed that compared with the bacterial community of red sufu and white sufu, the biomarker genera for both huase sufu were , and . Moreover, there were twenty-eight hubs for the huase sufu samples, and four of them were dominant genera: , , , . These results provide a new insight into our understanding of the bacterial diversity of huase sufu, and will facilitate the isolation, screening, and development potential bacterial strains for production of huase sufu.
