Title: Complementation characteristics of newly isolated mutants from two groups of strains of Clostridium perfringens. Author: Imagawa T, Tatsuki T, Higashi Y, Amano T. Journal: Biken J; 1981 Jun; 24(1-2):13-21. PubMed ID: 6272688. Abstract: 1. Mutants of a group were converted to b group by a second NG treatment. The resulting b group mutants could not produce the marker products that had been lost on the first NG treatment but could produce the others by complementation. 2. Mutants of b group were converted to constitutive mutants by a second NG treatment. No back mutation from b group was observed.[Abstract] [Full Text] [Related] [New Search]
