Different mutants of the catabolism of androst-4-ene-3,17-dione were produced in Nocardia restricta by action of y-rays and nitrosoguanidine. These selected mutants (acetate+-undrost-4-ene-3,17-dione-) are hexanoate-. Their behaviour is identical to the mutants selected as hexanoateacetatet which ar
