Melibiose is hydrolyzed exocellularly by an inducible exo-alpha-galactosidase in Azotobacter vinelandii.

T Y Wong1.   

Abstract

Azotobacter vinelandii hydrolyzed melibiose exocellularly, leading to an accumulation of free glucose and galactose in the medium. This enzyme could also be induced by galactose, raffinose, and stachyose. The alpha-galactosidase activity could be detected quantitatively by using p-nitrophenyl-alpha-galactopyranoside as a substrate for intact cells. Chloramphenicol totally inhibited the induction of this enzyme. However, benzyl alcohol inhibited the secretion of this enzyme but did not inhibit the biosynthesis of the enzyme.
