| 摘 要： | 探讨霉菌dh—B在开放体系中对酸性紫红染料的吸附脱色效果．在非灭菌条件下，考察pH值、染料浓度、温度及菌体投加量对吸附脱色的影响．研究表明：培养36h的菌种在pH为2．5，染料初始质量浓度为50mg／L，温度为30℃，菌体投加量为2．5∥L（湿质量）时，吸附脱色效果最好，脱色36h后脱色率可达到95％以上．同时霉菌曲一B在开放体系中表现出了极好的生长趋势和成球性能．

| Abstract: | The adsorption and decolorization effect of acid purple dye in an open system by mould dh-B is discussed in this paper including pH, initial concentration, temperature and amount of mycelium pellets were also studied to measure/calculate/evaluate the impact of adsorption and decolorization of dye in a non-sterile condition. The results showed that 36 hours of bacteria developed when pH was 2. 5, initial concentration of dyes was 50 mg/L, the temperature was 30 ℃, the pellet was 2. 5 g/L（ wet weight） which had the best adsorption and decolorization effect. The decolorization rate reached 95 % after 36 hours. Also, mold dh-B performed execellently with growth trends in the capacity of developing mycelium pellets. |
