ABSTRACT
Strains of Lactococcus lactis subsp. cremoris are used to produce yogurt containing exopolysaccharides with a sticky texture. When strain G3-2 producing exopolysaccharides was grown at elevated temperatures, a spontaneous mutant EPSC, which had lost exopolysaccharides biosynthesis, was isolated. Genomes of the two strains were determined to be composed of a 2.4-Mb chromosome and up to eleven plasmids, and it was revealed that one of the plasmids encoding the gene cluster for exopolysaccharides biosynthesis was lost selectively in EPSC.
