Abstract
|
|
|
|
The effects of nutritional sources on growth of Pseudomonas sp. P2 were investigated in medium containing biphentyl as a carbon source. To determine characterization of Pseudomonas sp. P2, the incubation time was determined to 100 h of the log phase in the growth curve. The optimal compositions for the growth of Pseudomonas sp. P2 degrading polychlorinated biphenyls (PCBs) were 1000 mg/L , 1000mg/L , 100mg/L ., 30mg/L ., 200mg/L NaCl, and 10mg/L .. Pseudomonas sp. P2 showed the degradability of 59.3%, 57.6%, 51.4%, and 48.7% at 500mg/L, 1000mg/L, 1500mg/L, and 2000mg/L of the PCBs within insulating oil after 100 h incubation under the optimum conditions, respectively.
