- W996379267 abstract "以从土壤中分离得到的黑曲霉（Aspergillus niger）菌株为研究对象,采用液体培养的方法,研究其在不同碳源、氮源、起始pH值、金属离子种类及浓度条件下对孟加拉红和水溶性色浆的脱色效果.结果表明,在以豆芽汁培养基为基本培养基、甘油为碳源、（NH4）2SO4为氮源、初始pH值为6.0～8.0条件下的脱色效果最佳,Cu2＋对菌体脱色有很强的抑制作用.根据活菌体和死菌体脱色能力的比较,结合菌体干重与脱色能力的相关性分析,初步推测该菌的脱色机理是菌丝吸附染料后,在菌丝体内对其进行降解;降解过程有限速酶参与,柠檬酸钠、酒石酸钠会抑制该酶的活性,而NH4＋对该酶有激活作用.关键词：黑曲霉;孟加拉红;色浆;脱色机理" @default.
