Biofilm formation by exopolysaccharide mutants of Leuconostoc mesenteroides strain NRRL B-1355.

Abstract excerpt

Leuconostoc mesenteroides strain NRRL B-1355 produces the soluble exopolysaccharides alternan and dextran in planktonic cultures. Mutants of this strain are available that are deficient in the production of alternan, dextran, or both. Another mutant of NRRL B-1355, strain R1510, produces an insoluble glucan in place of alternan and dextran. To test the effect of exopolysaccharide production on biofilm formation,...
