Activity of the enzymes involved in the synthesis of exopolysaccharide precursors in an overproducing mutant ropy strain of Streptococcus thermophilus.

Abstract excerpt

The activities of some enzymes belonging to the Leloir pathway, phosphoglucomutase, UDP-glucose pyrophosphorylase, UDP-galactose 4-epimerase and galactose 1-P uridyl transferase, were studied in a wild ropy, a non-ropy and an overproducing mutant ropy strain of Streptococcus thermophilus. These activities were assayed over successive culture transfers along with exocellular polysaccharide (EPS) production. The...
