The Adaptive Metabolism of D-Galactose in Aspergillus nidulans

Clive F. Roberts

Open publisher page 13 citations

Abstract

SUMMARY Methods are described for the growth of Aspergillus nidulans in submerged culture. In experiments with intact organisms D-galactose was oxidized by an inducible enzyme system; D-fucose was a poor inducer of this system. Mutants isolated by their failure to grow on galactose as sole carbon source were defective in the oxidation of galactose.
