摘要: Bacterial manganese (Mn) oxidation plays an important role in the global biogeochemical cycling of Mn and other compounds, diversity prevalence oxidizers have been well established. Despite many hypotheses why these bacteria may oxidize Mn, physiological reasons remain elusive. Intracellular levels were determined for Pseudomonas putida GB-1 grown presence or absence by inductively coupled plasma mass spectrometry (ICP-MS). oxidizing wild type P. had higher intracellular than non mutants under same conditions. a 5 fold increase compared to mutant GB-1-007 59 ∆2665 ∆2447. The is primarily associated with less 3 kDa fraction, suggesting it not bound protein. Protein cultures relatively similar, yet did survival when oxidatively stressed. This study first link homeostasis oxidative stress protection.
