黄孢原毛平革菌对三苯甲烷染料的生物脱色降解

利用黄孢原毛平革菌对代表性三苯甲烷染料进行处理。菌的3种品系BKM-F-767．ME446和OGC101对10．50．100mg／L不同浓度的碱性紫5BN，碱性副品红、甲酚红．溴酚蓝和孔雀绿等5种染料具有不同程度的脱色降解能力。碱性副品红和溴酚蓝最为敏感．低浓度(10～30mg／L)孔雀绿的脱色降解效果最好．碱性紫5BN则一般．而甲酚红似乎抵御菌的进攻。紫外一可见光测定表明：碱性紫5BN在BKM-F-1767的作用下。培养液发生吸收峰朝短波方向的移动．标志着染料分子结构发生变化。

Decolorization and Degradation of Triphenylmethane Dyes by Phanerochaete chrysosporium

The model triphenylmethane dyes have been treated with Phanerochaete chrysosporium. 3 strains of BKM-F-1767, ME446 and OGC101 could decolorize and degrade 5 kinds of dyes, as: Crystal Violet, Pararosa-niline, Cresol Red, Bromophenol Blue and Malachite Green of different concentrations (10mg/L, 50mg/L and 100mg/L) to some extent. Pararosaniline and Bromophenol Blue were the most sensetive; the decolorizing and degrading results of lower concentrations (10mg/ L-30mg/L) of Malachite Green were the best; Crystal Violet was ordinary; Cresol Red seemed resistant to the attack of this fungus. Absorbances in culture liquids were measured with ultraviolet-visible spectrom-etry, it showed that reacted on BKM-F-1767, the absorbance peaks of Crystal Violet underwent a hyp-sochromic shift,indicating the change of dye molecular structure.
