NH4+ derepression of azide resistant mutant of Azotobacter chroococcum.
Five azide resistant mutants of Azotobacter chroococcum were isolated after MNNG mutagenesis. These mutants varied in their ability to detoxify azide in the presence of NH4+ and this ability has been found to be directly related to NH4+ derepression.
