Chlorinated benzenes are wide spread in the environment and largely persistent against biological degradation. In this study a mixed bacterial population was enriched from a river polluted by industrial wastewater, that was able to degrade monochlorobenzene and the three isomers of dichlorobenzene. The mixed population was applied to a fluidized bed bioreactor containing an adsorptive carrier material (polyurethane foam with and without incorporated activated carbon). The total degradation of the chlorinated benzenes was determined quantitatively from the amount of chloride released. A maximum degradation rate of 150 mg/(l*d) was found. Both growth of the biomass on carriers and the composition of the population fluctuated. However, always species of Gram-negative genera Comamonas, Alcaligenes and Xanthobacter in addition to Gram-positive coryneform species of the Microbacterium/Cellulomonas group and Bacillus sp. were present.
