Culture medium for extracellular polysaccharide-producing lactic acid bacteria, method for producing extracellular polysaccharide-producing bacteria, extracellular polysaccharide, method for producing extracellular polysaccharide, and method for producing yogurt

摘要

PROBLEM TO BE SOLVED: To provide a culture medium to increase the production amount of exopolysaccharide by exopolysaccharide-producing lactobacillus, and also provide a method for manufacturing exopolysaccharide-producing lactobacillus.SOLUTION: The culture medium for exopolysaccharide-producing lactobacillus is prepared by adding formic acid or formic acid salt or both to skim milk or reconstituted skim milk or both, and/or by heating skim milk or reconstituted skim milk or both to make the total concentration of formic acid and formic acid salt or both to 0.4-10 mM. The exopolysaccharide-producing lactobacillus is cultured using the above-mentioned culture medium.
