An aerobic mixed culture removing phenol was developed and maintained with a biomass of 2900mg/l-3400 mg/l in a fed-batch reactor by feeding phenol 500 mg/l/day. The mixed culture (AS) consisted of two non-phenol bacteria and eight phenol degraders, of which 4 gram-negative rods and 4 gram-positive rods, that could remove about 96% of the fed phenol in 12 hours at 30 degrees C+/-3 degrees C. This paper also reports the stability of the consortium with respect to its constitution and phenol degradation.
