摘要:
对利用白腐真菌Coriolus versicolor的菌丝球来催化染料酸性橙的降解作了报道.首先进行了不同初始浓度酸性橙的降解实验.在实验范围内,降解率随着初始浓度的增高而增高,平均降解率在91%左右.建立模型拟合了同一温度下不同初始浓度酸性橙降解的过程.初始浓度在20.99到101.6 mg/L之间时,模型计算值与实验值大致吻合.考察了pH和温度对酸性橙降解的影响,发现菌丝球降解酸性橙的最适pH为6.0,温度以32℃左右为最佳.对补充了不同量碳源的酸性橙溶液进行重复分批降解实验表明,碳源的补充对重复分批降解是必不可少的.在重复过程中,降解率呈下降趋势.但在降解染料的同时添加适量的葡萄糖可以使菌丝的使用寿命显著延长.
