Growth associated exopolysaccharide expression in Lactococcus lactis subspecies cremoris Ropy352.

A natural lactococcal isolate, Lactococcus lactis ssp. cremoris Ropy352, has been previously shown to express two phenotypically distinct exopolysaccharides (ropy and mucoid). This natural isolate was cultured on various media to explore the carbon requirements for exopolysaccharide expression. Ropy exopolysaccharide expression was optimal when grown in… (More)
