Bacillus velezensis strain:Hao 2023 Genome sequencing. Bacillus velezensis

The strain is collected from the Rongcheng abalone fry collecting plate of the nursery plant of Shandong Rongcheng Xunshan Aquatic Products Group Co., Ltd. After the fermentation conditions were optimized, the high yield of exopolysaccharide was achieved. The aim of whole genome sequencing is to obtain the genetic background information of the bacterium, so as to further study the key genes in the sugar metabolism pathway of the bacterium. The functional element of the bacterium is further obtained, used for analysis of protein coding genes, subsystem analysis and function annotation, high-value polysaccharide is efficiently synthesized in a modular mode through metabolic engineering transformation, and the polysaccharide is used in industries such as medical treatment, industry and the like.
