Natural and synthetic progestagens in the environment have become a concern due to their adverse effects on aquatic organisms. Laboratory studies were performed to investigate aerobic biodegradation of norgestrel by bacteria from activated sludge in comparison with progesterone, and to identify their degradation products and biotransformation pathways. The degradation of norgestrel followed first order reaction kinetics (T 1/2 = 12.5 d), while progesterone followed zero order reaction kinetics (T 1/2 = 4.3 h). Four and eight degradation products were identified for norgestrel and progesterone, respectively. Six norgestrel-degrading bacterial strains (Enterobacter ludwigii, Aeromonas hydrophila subsp. dhakensis, Pseudomonas monteilii, Comamonas testosteroni, Exiguobacterium acetylicum, and Chryseobacterium indologenes) and one progesterone-degrading bacterial strain (Comamonas testosteroni) were successfully isolated from the enrichment culture inoculated with aerobic activated sludge. To our best knowledge, this is the first report on the biodegradation products and degrading bacteria for norgestrel under aerobic conditions.

“…Li et al (2008) also showed that 100 mg/l chlorpyrifos was degraded to an undetectable level in 24 h by Liu et al (2012) that the degradation rate was decreased slowly with the concentration of chlorpyrifos being increased from 100 to 150 mg/l. The degradation of chlorpyrifos by P. fluorescence, B. melitensis and B. subtilis was 43, 45 and 56 %, respectively, after 10 days of incubation and 89, 87 and 85 %, respectively, after 30 days of incubation, when 50 mg/l chlorpyrifos was supplied as sole source of carbon .…”

“…At 25 and 50 mg/l chlorpyrifos, maximum microbial growth was attained on the 5th day and thereafter growth declined during degradation of chlorpyrifos by Pseudomonas aeruginosa (Huang et al 2000). Li et al (2008) reported that approximately 98 % of chlorpyrifos was degraded within 10 days by seven bacterial isolates belonging to Pseudomonas genus collected from soil. Figure 2 presents the both bacterial growth and degradation of chlorpyrifos for the isolate B. caryophylli BG4 when 20 and 50 mg/l chlorpyrifos were used, respectively, Table 2 Pesticide residues (lg/l) in water samples collected from near of the vegetable fields of Savar Upazila as sole carbon source, respectively.…”

“…Though a little information exists regarding the ability to degrade chlorpyrifos by bacteria belonging to Burkholderia and Brevundimonas species, some studies showed a lot of information about the efficient degradation of chlorpyrifos performed by the different species of Pseudomonas (Digrak et al 1995;Huang et al 2000;Li et al 2008;Rani et al 2008;Xu et al 2008;Liu et al 2012). Chlorpyrifos has also been reported to be degraded cometabolically by bacteria, which needs extra carbon sources (Richins et al 1997;Mallick et al 1999).…”

Determination of selected pesticides in water samples adjacent to agricultural fields and removal of organophosphorus insecticide chlorpyrifos using soil bacterial isolates

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.
