Isolation of formaldehyde-degrading bacteria and the evaluation of the degradation characteristics

다국어 초록 (Multilingual Abstract)

A formaldehyde-degrading bacteria strain, B1, was isolated. Strain B1 was characterized morphologically,physiologically and biochemically, and it was identified as Pseudomonas putida. Then, the formaldehydebiodegradation characteristics were evaluated in a biofilter. A formaldehyde removal rate above 90% wasmaintained when inlet loading was below 38.9 mg L 1 h 1. In addition, strain B1 quickly becamedominant bacteria when the reactor was restarted following a 30-days’ disruption, illustrating that thestrain is both adaptable and resilient. The numerical simulation results demonstrate that the maximumdegradation rates in the biofilter with strain B1 are betterfitted with the Haldane model.
