Summary

Catalase deficient mutants (kat) ofSalmonella typhimurium have been isolated. The mutationskatA1, katC6 andkatD9 appear to map at about minute 10 on theSalmonella chromosome. ThekatC6 andkatD9 lesions are complemented by theE. coli F′128 (lac+ pro+) episome but thekatA1 lesion is not.KatB2 maps at about minute 100. None of the mutants are oxygen sensitive; they grow as well as wild type bacteria, even when aerated.
