Abstract

Penicillinase production in strains of bacillus in which such production is constitutive, as well as in strains in which it is inducible, was found to be a function of the type of penicillin to which the organism was exposed. A repressive effect in two constitutive strains was noted. An increase in the level of penicillinase produced by the constitutive strains was noted for some of the penicillins.
