Induction, isolation, and characterization of aspergillus niger mutant strains producing elevated levels of beta-galactosidase.

K M Nevalainen.   

Abstract

An Aspergillus niger mutant strain, VTT-D-80144, with an improvement of three- to fourfold in the production of extracellular beta-galactosidase was isolated after mutagenesis. The production of beta-galactosidase by this mutant was unaffected by fermentor size, and the enzyme was also suitable for immobilization.
