ABSTRACT Azotobacter vinelandii produces two detectable catalases during growth on minimal medium. The heat-labile catalase expressed during exponential growth phase was identified as a KatG homologue by liquid chromatography-tandem mass spectrometry (LC-MS/MS) using a mixed protein sample. The seco...
