Growth Stimulation of Lactobacillus Species by Lactic Streptococci1

RESUMO
Cell extracts of Streptococcus species important in cheese starters stimulated the growth of Lactobacillus species common to Cheddar cheese. All Lactobacillus strains employed, with the exception of a strain of L. casei, were significantly stimulated by a strain of S. diacetilactis. L. casei was highly stimulated by both a strain of S. lactis and a strain of S. diacetilactis. The stimulant(s) was dialyzable and was partially inactivated by heat. The stimulatory principle was active at 10 C, indicating that the stimulatory effect may be influencing the growth of lactobacilli in Cheddar cheese during curing. Viable Streptococcus cells did not inhibit the growth of Lactobacillus species.
