Production of Exopolysaccharides by Strains of Streptococcus thermophilus
Two strains of Streptococcus thermophilus producing capsular and capsular-ropy exopolysaccharides (EPS) were examined for their growth and EPS production in M17 medium supplemented with glucose, galactose or lactose and incubated at 30, 37 or 42°C for 24 hours. Growth parameters (viable cells, OD, l...
