摘　　要：实验研究了不同条件下海洋光舍细菌的混合菌种对五种活性染料的脱色效果。结果表明，海洋光舍细菌耐盐性较好，对五种染料都有很好的脱色效果。温度对各类染料影响不同，但五种染料都在30～35℃时达到最佳脱色效果。菌种适应的PH值范围广，驯化后活性增强。在100mg／L的浓度下，染料X-3B对细菌生长没有明显的抑制作用。The effects of ocean photosynthetic bacteria on the decolourization of five dyes under different conditions were studied. The results show that ocean photosynthetic bacteria could tolerate high salinities and five different dyes were decolorized by it. The effects of temperature on the dyes of different structures are different. The decolourization rate was optimal at temperature 30-35℃, X-3B was degraded well under the condition of PH ranging from 3 to 10. The activity of tamed bacteria was better. X-3B did not inhibit cell growth when its concentration was ≤100 mg/L.
