The ability of the enriched microbial consortium to degrade phenol was measured under batch conditions. All biodegradation experiments using the microbial consortium (CF1) was carried out in 250 ml Erlenmeyer flask containing 100ml of MSM with phenol concentration varying from 100mg l1 to 1000mgl1. The flasks are incubated at 35 C under agitation condition (150 rpm), samples were withdrawn at regular time interval, centrifuged and analyzed for residual phenol concentration. Each experiment was carried out until complete phenol degradation.
