| Abstract | Genetically engineered strains of Pseudomonas, which could degrade the various aromatic hydrocarbons, were acclimated to the synthetic wastewater with increasing substrate concentration. All of the tested strains except KUD101 showed 70-90% of the COD removal efficiencies. Acclimated strains, Pseudomonas putida KUD106, KUD107 and KUD108 were inoculated into the ordinary activated sludge and these sludges were used in the dyeing or alkylbenzene wastewater treatment system. In the case of the wastewater containing alkylbenzene compounds, COD removal efficiency was 12-14% higher than that of the ordinary activated sludge, while it was not effective for dyeing wastewater. On the other hand, the floc formation of the activated sludge inoculated with genetically engineered strains was more rapid in both wastewaters tested than that of the activated sludge by the ordinary natural strains. | ||
