摘要
通过14C标记底物的矿化实验发现青霉菌对多聚芳香族化合物有一定降解能力,本研究以3种偶氮和蒽醌型活性染料为作用底物,结果表明,青霉菌G-1 (Penicillium sp.)对染料进行吸附,吸附等温线符合Langmuir模型,最大理论吸附量(Qmax)可达169.5~243.9mg/g干重,被吸附染料最早在第4d完全脱色降解,有菌丝和去除菌丝的培养液中再次加入染料,均可在20~30h内使染料完全脱色降解.
The definite degradability of Penicillium sp. on polycyclic aromatic compounds has been reported through mineralization experiment with 14C marked substrate. In this study, three azo or anthraquinone activated dyes were used as the substrate. The results showed that the penicillium sp. first adsorpted the dyes with the adsorption isotherm conformed to Langmuir model and the maximum adsorption capacity (Qmax) might reach up to 169.5 [similar to] 243.9mg/g dry weight. The adsorbed dyes were decolorized and degraded completely in four days, and in the degradation systems with mycelium and without mycelium the dyes added again could be decolorized and degraded in 20 [similar to] 30h.
