Use of chemostat for selection ofStreptomyces chrysomallus mutants altered in the induction of D-glucose isomerase

Abstract
D-glucose isomerase ofStreptomyces chrysomallus PL45 is inducible by D-xylose only. In mutants obtained by means of a selection procedure in a chemostat the isomerase was induced in xylose-free medium containing glucose as carbon source.
