外源调控对白腐真菌生物膜反应器的影响研究

Study on the Effects of Nutrient and Enzymatic Inducer Regulations in a White Rot Fungal Biofilm Reactor

研究了碳源、氮源及诱导物调控对白腐真菌生物膜反应器处理活性黑KNB染料废水的锰过氧化氢酶(MnP)活性及脱色率的影响。结果表明:葡萄糖、酒石酸铵和Mn^(2+)浓度分别为10g/L、0.2g/L和0.2mmol/L时,MnP活性及脱色率达到最高,分别为92.1 U/L及98.9%。MnP活性与脱色率之间有较好的正相关性,表明MnP是该体系的降解功能主体。

Effects of nutrient and enzymatic inducer regulations on MaP＇s activity and decolorisation had been studied in a white rot fungal biofilm reactor. It was demonstrated that when the concentrations of the glucose, tartaric acid ammonium, and Mn^2＋ were 10g/L, 0.2g/L and 0.2mmol/L, MnP＇s activity and reactive black KNB dye decolorisation was the highest, each was 92.1U/L and 98.9%. There was better positive relevance between MnP＇s activity and dye decolorisation, which meant that MnP played the key parts in dye decolorisation.
