The contemporaneous presence of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus affected the growth kinetics of Saccharomyces cereÕisiae PZ2 and the metabolic products of their growth were quantitatively and qualitatively different from those produced by single strains inoculated alone. S. cereÕisiae can grow in milk without using lactose or galactose. In particular, the presence of peptides seems to be sufficient to ensure its growth. The growth of S. cereÕisiae with lactic acid bacteria is characterised by stimulatory effects that involve both yeast and bacteria. However, the release of galactose by lactic acid bacteria does not seem to be the core metabolic event of these stimulatory effects on S. cereÕisiae.

Abstract
The contemporaneous presence of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus affected the growth kinetics of Saccharomyces cereÕisiae PZ2 and the metabolic products of their growth were quantitatively and qualitatively different from those produced by single strains inoculated alone. S. cereÕisiae can grow in milk without using lactose or galactose. In particular, the presence of peptides seems to be sufficient to ensure its growth. The growth of S. cereÕisiae with lactic acid bacteria is characterised by stimulatory effects that involve both yeast and bacteria. However, the release of galactose by lactic acid bacteria does not seem to be the core metabolic event of these stimulatory effects on S. cereÕisiae.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
