“…This confirms the results by Pronk et al [33] whereby neutral compounds were assumed to sorb to both AEMs and CEMs. Above pH 10, ES degradation results from cleavage of the cyclic sulfite group [10] leading to the formation of ES diol. This process is accelerated by NaOH addition.…”

Endosulfan (ES) is a micropollutant found in reverse osmosis concentrates from water reuse applications. Electrodialysis (ED) can remove and recover charged solutes from such concentrates.While polar compounds cannot normally be removed, their fate in ED is important as they can contribute to membrane fouling/poisoning and be released during cleaning. High adsorption of ES to ED membranes was observed. Consequently, the influence of solution pH and presence of humic acid (HA) on sorption mechanisms of ES to ion-exchange membranes during batch sorption isotherm and ED experiments were investigated systematically. ES-membrane partition coefficients * Current address: Faculty of Engineering, University of Wollongong, Wollongong NSW 2522, Australia 2 (log K AEM/CEM ) quantified through sorption isotherm experiments suggested that ES sorption was resultant of membrane catalysed ES degradation, hydrogen bonding and cation-π interactions between ES and membrane functional groups. ES sorption at pH 7 (550 µg/cm 3 ) was greater than sorption at pH 11 (306 µg/cm 3 ) due to alkaline hydrolysed ES and resultant decrease in bonding capacity with the membranes at high pH. The presence of HA reduced sorption at pH 7 (471 µg/cm 3 ) and 11 (307 µg/cm 3 ) due to HA competitive sorption. Partial membrane desorption was noted in isotherm (≤ 20%) desorption experiments and was dependent on the initial mass sorbed, solvent pH and resultant membrane interactions.

“…It is used in many countries throughout the world for the control of pests on fruits, vegetables, tea, tobacco, and cotton (Antonious and Byers, 1997;Sethunathan et al, 2002). Because of such abundant usage, and the potential for accumulation in the environment (endosulfan is not readily detoxified by soil microorganisms), residues are detectable in soils, sediments, and crops at harvest time (Goebel et al, 1982;U.S. Department of Health and Human Services, 1990).…”

It has largely been responsible for the "green revolution", i.e. the massive increase in food production obtained from the same surface of land with the help of mineral fertilisers (nitrogen, phosphorus, potassium), more efficient machinery and intensive irrigation. The use of pesticides helped to significantly reduce crop losses and to improve the yield of crops such as corn, maize, vegetables, potatoes and cotton. Notwithstanding the beneficial effects of pesticides, their adverse effects on environmental quality and human health have been well documented worldwide and constitute a major issue that gives rise to concerns at local, regional, national and global scales (Planas et al., 1997; Huber et al., 2000; Kidd et al., 2001; Cerejeira et al., 2003). Residues of pesticides contaminate soils and water, persist in the crops, enter the food chain, and finally are ingested by humans with foodstuffs and water. Furthermore, pesticides can be held responsible for contributing to biodiversity losses and deterioration of natural habitats (Sattler et al., 2006). There have been reported instances of pest resurgence, development of resistance to pesticides, secondary pest outbreaks and destruction of non-target species. Despite the fact that pesticides are also applied in other sectors, agriculture can undoubtedly be seen as the most important source of adverse effects (Hoyer and Kratz, 2001; cited in Sattler et al., 2006).The application of different pesticides varies with the region. For instance, in North Ameri...

“…However, it has a relatively reactive cyclic sulfite diester group and can serve as a good sulfur source (Sutherland et al, 2000). The removal of sulfur moiety from the endosulfan substantially reduced its vertabrate toxicity and therefore helped in detoxification of the compound (Goebel et al, 1982;Singh and Singh, 2011).The isolated bacterial strains could degrade about 56.7-88.5% of 100 mg/l of α-endosulfan in 10 days of incubation. The difference in degradation capability of various strains may be due to difference in enzyme system and/or difference in their growth rate (Bhattacharjee et al, 2014).…”

A b s t r a c tExtensive applications of organochlorine pesticides like endosulfan have led to the contamination of soil and environments. Five different bacteria were isolated from cockroaches living in pesticide contaminated environments. According to morphological, physiological, biochemical properties, and total cellular fatty acid profile by Fatty Acid Methyl Esters (FAMEs), the isolates were identified as Pseudomonas aeruginosa G1, Stenotrophomonas maltophilia G2, Bacillus atrophaeus G3, Citrobacter amolonaticus G4 and Acinetobacter lwoffii G5. This is the first study on the bacterial flora of Blatta orientalis evaluated for the biodegradation of α-endosulfan. After 10 days of incubation, the biodegradation yields obtained from P. aeruginosa G1, S. maltophilia G2, B. atrophaeus G3, C. amolonaticus G4 and A. lwoffii G5 were 88.5% , 85.5%, 64.4%, 56.7% and 80.2%, respectively. As a result, these bacterial strains may be utilized for biodegradation of endosulfan polluted soil and environments. 64developed resistance to pesticides. If this is true, we can isolate new and effective α-endosulfan degrading bacteria from cockroaches' microflora and these isolates can be used for the biological treatment of waters and soils polluted with endosulfan and other insecticides. Experimental Material and MethodsChemicals. α-endosulfan and reagents were purchased from Sigma-Aldrich (St Louis, MO, USA). All solvents used were of the highest analytical grade and were employed without further purification. The stock α-endosulfan solution was prepared in acetone and used for all the experiments. The chemical structure and the most important physical parameters of endosulfan are summarized in Fig. 1 O, 24 (Siddique et al., 2003). After 7 days, 5 ml of each culture was re-inoculated into new α-endosulfan-NSM medium and further incubated at 30°C for 7 days. This subculture was repeated under the same culture conditions, and then an aliquot (0.2 ml) from each culture was applied to solid α-endosulfan-NSM for isolation of single colonies.Identification of endosulfan degrading microorganisms. α-endosulfan degrading bacterial isolates were identified by various tests, such as pigment formation, Gram staining, nitrate reduction, catalase and oxidase tests, and starch hydrolysis. Biochemical reactions were conducted according to Benson (2001). Biochemical activities were determined according to the recommended scheme of Bergey's Manual of Determinative Bacteriology (Holt et al., 1994). Identification was confirmed by the fatty acid analysis for all bacterial isolates. Fatty acid methyl ester (FAME) profiles of each bacterial strain were identified by comparing the commercial databases (Tripticase Soy Broth Agar 40) with the MIS software package. The identity of bacterial strains was revealed by computer comparison of FAME profiles of the unknown test strains with those in the library. FAMEs were separated by gas chromatography (HP6890, Hewlett Packard, Palo Alto, CA, USA) with a fused-silica capillary column (25 m × 0.2 mm) with cr...
