Induction of Xylose Reductase in Germinating Spores of Penicillium chrysogenum

Abstract
Studies with cell-free extracts of P. chrysogenum have shown that the enzyme responsible for the reduction of xylose to xylitol is inducible when the spores are germinated on a simple mineral-salts medium with xylose as the only C source. The enzyme induction was inhibited when high levels of glucose were in the medium and was stimulated with low levels of glucose.
