폴리우레탄 바이오필터에 의한 악취성 피리딘 분해 및 피리딘 분해세균의 분리


Pyridine could be successfully removed in the polyurethane(PU) biofilter inoculated with activated sludge treating industrial wastewater. The elimination capacity for pyridine in the PU biofilter was approximately 27 g m⁻³ h⁻¹ at the tested loading range, The pH value of drainage was increased due to the accumulation of ammonia which was one of the metabolites of pyridine, Four pyridine-degrading bacteria were isolated from the PU biofilter, and they were closely related with Rhodococcus pyridinivorans(98~99% similarity). The specific growth rate of the isolate in the medium supplemented with pyridine as a sole carbon and energy source were ranged from 0.038 h⁻¹ to 0.051 h⁻¹.
