Several environmental factors influencing the growth of two kinds of Actinomycetes (S.chromofuscus All, S.setonii 75Vi2), and their ability of removing 2, 4-dichlorophenol (2, 4-DCP) were investigated in batch cultures.The characterization of extracellular peroxidases produced by the objective fungi was also investigated. Optimal p H, temperature and nutritional conditions for the growth of each fungi and the basic feature of extracellular peroxidases were obtained. And it was concluded that 2, 4-DCP hindered growth of fungi and it could be removed by the objective fungi. The extracellular peroxidase produced by S.chromofuscus All may contribute to the removal of 2, 4-DCP.
