[Nuclease biosynthesis and growth of Serratia marcescens in the presence of 2-(p-aminobenzenesulfonamide)-thiazole].

The biosynthesis of nuclease in Serratia marcescens has been studied under the conditions of purine synthesis inhibition with 2-(p-aminobenzenesulfonamide)-thiazole. The addition of this sulfonamide to S. marcescens at different growth stages is found to inhibit both culture growth and nuclease synthesis.
