title: Degradation and decolorization of monosodium glutamate wastewater with Coriolus versicolor.
abstract: Degradation and decolorization of monosodium glutamate wastewater (MSGW) with Coriolus versicolor were firstly carried out. The effects of various operation parameters namely wastewater concentrations, pH, culture time and incidence of sterilization on maximum percentage of degradation and decolorization of wastewater were investigated. Studies of mycelium and enzyme for C. versicolor degradation and decolorization were estimated in this study. Ten percentage of wastewater concentration and pH = 5.0 were found to be the most suitable ones among the other experiments. The highest degradation and decolorization efficiency of wastewater was obtained at the fifth day of cultivation, which was displayed with more than 70% chemical oxygen demand removal, 83% total sugar removal and 55% color removal, respectively. Sterile operation had no remarkable effect on the degradation and decolorization efficiency for C. versicolor. Mycelium and the extra cellular fungal enzyme were both necessary for the degradation and decolorization of MSGW. C. versicolor possesses great potential and economic advantages in MSGW treatment.
