The results showed that temperature 25 - 30 , ph7 . 0 , anaerobic and illuminated conditions were optimum for decolorization . when reactive violet kbr was decolorized as sole source of carbon and energy of n strain , the decolorization rate of reactive violet kbr was significantly correlative to cell concentration , however the decolorization specific activity of n strains was not affected markedly by cell concentration 结果表明,该菌株生长细胞脱色的最佳条件为温度25 - 30 , ph7 ,厌氧条件下的脱色率远远高于好氧条件下的脱色率。染料作为该菌株唯一的碳源和能源脱色时,脱色率与细胞浓度呈极显著相关,细菌脱色比活率保持在较恒定的水平。
