The decolorization of methyl red directed toward rapid reduction of azo group by a mixed culture of Bacillus sp. and Pseudomonas stutzeri was investigated. The improvement of the decolorization of methyl red was obtained by a mixed culture (a mixed culture 2) with particular proportion of two bacteria (Bacillus sp. and Pseudomonas stutzeri). The mixed culture 2 was grown in a LB medium with methyl red. The improvement of the decolorization of methyl red was obtained only by the growing mixed culture and not obtained by the mixture of the resting cells.
研究了芽孢杆菌属和施氏假单胞菌的混合培养物对甲基红的脱色作用，该作用是通过偶氮基团的快速还原实现的。通过具有特定比例的两种细菌（芽孢杆菌属和施氏假单胞菌）的混合培养物（混合培养物2），甲基红的脱色效果得到了改善。混合培养物2在含有甲基红的LB培养基中生长。甲基红脱色效果的改善仅通过生长的混合培养物实现，而静止细胞的混合物则无法实现。
