In this work, the extracellular decolorization of aniline blue, a sulfonated triphenylmethane dye, by Shewanella oneidensis MR-1 was confirmed. S. oneidensis MR-1 showed a high capacity for decolorizing aniline blue even at a concentration of up to 1,000 mg/l under anaerobic conditions. Maximum decolorization efficiency appeared at pH 7.0 and 30 °C. Lactate was a better candidate of electron donor for the decolorization of aniline blue. The addition of nitrate, hydrous ferric oxide, or trimethylamine N-oxide all could cause a significant decline of decolorization efficiency. The Mtr respiratory pathway was found to be involved into the decolorization of aniline blue by S. oneidensis MR-1. The toxicity evaluation through phytotoxicity and genotoxicity showed that S. oneidensis MR-1 could decrease the toxicity of aniline blue during the decolorization process. Thus, this work may facilitate a better understanding on the degradation mechanisms of the triphenylmethane dyes by Shewanella and is beneficial to their application in bioremediation.
