Title

BIODEGRADATION OF CYPERMETHRIN BY PSEUDOMONAS IN A BATCH ACTIVATED SLUDGE PROCESS

Pages

  371-380

Abstract

 The BIODEGRADATION of CYPERMETHRIN (20 to 125 mg/L) in EFFLUENT using batch ACTIVATED SLUDGE was studied. Degradation was found to occur to a great extent only in the presence of PSEUDOMONAS (IES-Ps-1) culture. Under aerobic conditions using MECHANICAL AERATORS, CYPERMETHRIN (20 mg/L) was almost completely degraded in just over 48 h at ambient temperature. Further loading of organic compound in subsequent experiments demonstrated that IES-PS-1was capable to degrade 82 % CYPERMETHRIN at 40 mg/L dose in approximately 48 h. When the concentration was increased to 80 mg/L, 50% degradation of this compound was observed. Over this time period the cells could utilize only 17 % of CYPERMETHRIN when it was given 125 mg/L, respectively. These findings indicate that increased concentration of CYPERMETHRIN has a marked effect on BIODEGRADATION performance of IES-Ps-1 with a modest increased in the duration of lag phase, but did not lead to complete inhibition or cell death. These results proved that IES-Ps-1 is responsible for CYPERMETHRIN degradation. Such finding may be useful in designing a scale-up in situ or on-site hazardous waste bioremediation process for field application.
