Abstract
|
|
|
|
The effects of culture broth filtrates, sugar changes and utilizationon the growth and acid production of P. freudenreichii KFCC 31227 and L. acidophilus KFCC 32825 were investigated in S.G.Y. (Skim milk, glucose, yeast extract) and SMW (skin milk whey)medium by the single and mixed cultures. The growth and acid production bye mixed culture and in cultured broth filtrate of the other party were more affected than those of single culture and self-cultured broth filtrate. When the two strains were cultured, P. freudenreichii KFCC 31227 utilized with lactose more than glucose and L. acidophilus KFCC 32825 was glucose more than lactose in the growth and acid production. The mixed culture of two strains was more affected to sugar utilization than single culture. This result was considered due to the synergistic effect by interaction of these two strains in mixed culture.
