title: Complete genome sequence of Lactobacillus helveticus MB2-1, a probiotic bacterium producing exopolysaccharides.
abstract: Lactobacillus helveticus MB2-1 is a probiotic bacterium producing exopolysaccharides (EPS), which was isolated from traditional Sayram ropy fermented milk in southern Xinjiang, China. The genome consists of a circular 2,084,058bp chromosome with no plasmid. The genome sequence indicated that this strain includes a 15.20kb gene cluster involved in EPS biosynthesis. Genome sequencing information has provided the basis for understanding the potential molecular mechanism behind the EPS production.
