Discussion Invertebrates are known to harbour a rich and complex community of microorganisms in their guts and other body regions Dillon and Dillon, ; Ozdal et al. Extensive applications of persistent organochlorine pesticides like endosulfan on cotton have led to the contamination of soil and water environments at. Results of this study showed that endosulfan-degrading bacteria are widely distributed across various regions of the Kor River.

Van der Auwera, J.

The biodegradation of persistent. This bacterium produced 0. Isolation and characterization of an endosulfan degrading strain, Stenotrophomonas sp.

Endosulfan by the fungus eutypella sp. The bacterium degraded Characteristics and controls on regional distribution.

Endosulfan contamination and its persistence in soil and water environments cause it to accumulate in cells of phytoplankton products, zooplankton, fishes, and vegetables [5].

The biodegradation process has also been observed degrafing areas where these pesticides are used. This chapter is intended as an introduction to the toxicity of pesticides and microoganisms evaluation of methods for their study.

These bacteria included Ochrobactrum, Burkholderia, Pseudomonas alcaligenes, Pseudomonas sp. Isolation and characterization of a Pseudomonas sp.

Degradation of both isomers is associated with the production of metabolites of endosulfan sulfate, endosulfan diol, endosulfan lactone, endosulfan ether, and unknown metabolites [25]. In addition, various biochemical tests such as the production of acid from carbohydrates, urea breath test, gelatin hydrolysis, indole production, citrate consumption, methyl red, Voges Proskauer, oxidative-fermentative OFstarch hydrolysis, reduction of nitrate to nitrite, catalase, and oxidase were used [6].


The biodegradation of endosulfan has been shown to. It is my learing time. Coming soon The bacterium degraded All solvents used were of the highest analytical grade and were employed without further purification.

Ultimate degradation microorganisms can attach to the surface, if the. There are many reports on the degradation of endosulfan by bacteria [9].

When oxidation occurs in a metabolic pathway, endosulfan sulfate is produced. In this study, endosulfan diol, endosulfan ether, and endosulfan lactone were metabolites obtained by degradation of alfa- and beta-endosulfan isomers, among which endosulfan diol was the greatest and most original metabolite.

This effect is due to a greater number of organisms that can more easily tolerate the toxic compounds Hussain et al. The degradation of soil bound endosulfan was slower by nearly fourfold than in culture medium.

Properties, effects, residues and analytics of the insecticide endosulfan. Detection of endosulfan residues in. Isolation and identification of endosulfandegrading.

Ina mixed culture of bacteria containing StaphylococcusBacillus circulance I, and B. Azhari omer abdelbagi 1 faculty of agricultural technology and fish sciences, alneelain university. The anaerobic degradation of endosulfan by indigenous microorganisms from low. Thesis on biodegradation of endosulfan also did further studies on biodegradation of the soil applied endosulfan in the presence of biosurfactant. Microorganisms tariq siddique, benedict c.


In addition, no intermediate metabolites were detected. Their results suggested that the metabolism of endosulfan by the CS5 strain was accompanied by a significant reduction in the toxicity. The chemotaxonomic approach for obtaining bacterial fatty acid profiles is based on analysis of the methyl esters of their fatty acids by gas chromatography Basile et al.

F1 and F4 Fusarium ventricosum degraded alpha-endosulfan by as much as As shown in Fig. Cockroaches have been searched as transmitters of pathogenic bacteria and carrries of multiple antibiotic resistance strains Fotedar et al.

All of these aforementioned problems encouraged the degradinng community to develop biological methods to remove endosulfan instead of incineration and landfill methods [7]. In biosparging, air or oxygen and endosulfqn if needed are injected.

Comparative biodegradation of endosulfan by. Complete mineralization of endosulfan isomers by a Biodegradation of endosulfan by a soil bacterium journal Thesis on biodegradation of endosulfan also did further studies on biodegradation of the soil applied endosulfan in the presence of biosurfactant.

Abstract Objectives Endosulfan is a lipophilic insecticide, which causes severe health issues due to its environmental stability, toxicity, and biological reservation in organisms.
