abstract：:A number of catalase-deficient mutants of Escherichia coli which exhibit no assayable catalase activity were isolated. The only physiological difference between the catalase mutants and their parents was a 50- to 60-fold greater sensitivity to killing by hydrogen peroxide. For comparison, mutations in the xthA and rec...
