Induction of intracellular and extracellular beta-galactosidase activity in Phycomyces blakesleeanus (original) (raw)

PubMed, 1989

Abstract

The inductive effect of different sugars on beta-galactosidase synthesis in Phycomyces blakesleeanus has been studied. The enzyme was inducible by galactose and fructose. When grown on these sugars the enzyme level was 10-20 times greater than when grown on glucose. We have detected both intra- and extracellular beta-galactosidase activity when Phycomyces blakesleeanus was grown on galactose, but only extracellular beta-galactosidase activity when grown on fructose plus lactose.
