【 摘 要 】

This work aimed to investigate the capacity of Pleurotus ostreatus DSM 1833 to degrade 2,4-dichlorophenol, important pollutant found in the wastewaters of the paper and cellulose industry. Using a factorial design 2², the concentrations of glucose and 2,4-dichlorophenol varied between 0 and 10g.L-1 and 5 and 30mg.L-1, respectively. The best global biodegradation rate was obtained using 30 mg.L-1 of 2,4- dichlorophenol in the absence of glucose. This culture medium was used for scaling up the process, resulting in a global biodegradation rate of 0.47mg.L-1.h-1. A comparative test between an inoculated medium and an abiotic control demonstrated that 54.1% of 2,4- dichlorophenol degradation could be attributed to the presence of P. ostreatus.
