The Thermostability of Penicillinase Free

Abstract

SUMMARY: Extracellular penicillinase produced by the growth of five different strains of the genus in casein hydrolysate is rapidly inactivated at 100°, but can be strikingly protected against such inactivation by addition of 1% gelatin or high molecular weight substances present in tryptic digest and meat infusion broth.
