“…Chlorpyrifos [O,O-diethyl O-(3,5,6-trichloro-2-pyridyl) phosphorothioate] is used worldwide as an agricultural insecticide (Cho et al 2002). There are numerous studies of chlorpyrifos insecticide degradation by microorganisms (Singh et al 2004;Lakshmi et al 2008;Anwar et al 2009;Briceño et al 2012). The aim of this paper is to determine the concentration of the selected pesticide residues in agricultural water samples of Savar Upazila and to degrade chlorpyrifos using soil bacteria.…”

The use of pesticide for crops leads to serious environmental pollution, therefore, it is essential to monitor and develop approaches to remove pesticide from contaminated environment. In this study, water samples were collected to monitor pesticide residues, and degradation of chlorpyrifos was also performed using soil bacteria. Identification of pesticide residues and determination of their levels were performed by high-performance liquid chromatography with photodiode array detector. Among 12 samples, 10 samples were found contaminated with pesticides. Chlorpyrifos was detected in four tested samples and concentrations ranged from 3.27 to 9.31 lg/l whereas fenitrothion ranging from (Below Detection Limit, \0.1 lg/ l) to 33.41 lg/l in the tested samples. Parathion was found in two tested samples at the concentration of 0.73 and 6.23 lg/l. None of the tested samples was found contaminated with Methoxychlor, DDT and Ethion. Three soil bacterial isolates, Pseudomonas peli BG1, Burkholderia caryophylli BG4 and Brevundimonas diminuta PD6 degraded chlorpyrifos completely in 8, 10 and 10 days, respectively, when 20 mg/l chlorpyrifos was supplied as sole source of carbon. Whereas, BG1, BG4 and PD6 took 14, 16 and 16 days, respectively, for complete removal of 50 mg/l chlorpyrifos. Chlorpyrifos degradation rates were found maximum by all three isolates at 2nd day of incubation for both tested concentrations. The results of the present study suggest the need for regular monitoring of pesticide residues in water, to protect the aquatic environment. Chlorpyrifos degrading bacterial isolates can be used to clean up environmental samples contaminated with the organophosphate pesticides.

“…Actinomycetes Streptomycetes strains have been known for their profound industrial application. Strains degrading chlorpyrifos were isolated (Briceno et al, 2012), ability to degrade pesticide was established in agar medium, interestingly degradation was found to be modulated by the changes in the pH of the cultivation medium (Briceno et al, 2012). Yet another pesticide Profenofos degrading bacteria were isolated by enrichment technique.…”
