The present invention discloses an application of a mixed bacterial fermentation broth in the decolorization of triphenylmethane dyes. The mixed bacterial fermentation broth comprises a mixture of fermentation broths of one or more of Bacillus subtilis, Pseudomonas or Actinomycetes. The mixed bacterial fermentation broth constructed in the present invention for the efficient decolorization of triphenylmethane dyes can decolorize more than 70% of water-soluble aniline blue under both static and shaking conditions, and can tolerate a pH of about 4-8 and a high concentration of water-soluble aniline blue. In addition, the bacterial fermentation broth also has a good decolorization effect on other triphenylmethane dyes. It can decolorize more than 90% of basic fuchsin and malachite green within 48 hours, and also has a certain decolorization effect on three triphenylmethane dyes, namely methyl violet, acid blue 1 and acid red 94. The types of triphenylmethane dyes decolorized are significantly more than those of the reported microbial strains, showing high broad-spectrum property, and having the possibility of being actually applied to solve triphenylmethane dye wastewater.
