Soil samples contaminated with pesticides were collected from agricultural fields in and around Pudukkottai district, TamilNadu. Samples were inoculated into mineral salts medium with Lambda cyhalothrin as the sole source of carbon and incubated for 12 days. Intermittent addition of pesticide was carried out for enrichment of cultures. Bacteria capable of degrading lambda cyhalothrin were isola...

In methanogenic environments degradation of fatty acids is a key process in the conversion of organic matter to methane and carbon dioxide. For degradation of fatty acids with three or more carbon atoms syntrophic communities are required. This chapter describes the general features of syntrophic degradation in methanogenic environments and the properties of the microorganisms involved. Syntrop...

Hydrophobic organic soil contaminants such as polycyclic aromatic hydrocarbons (PAH) are poorly mobile in the aqueous phase and tend to sorb matrix, resulting low bioavailability. Some filamentous fungi efficient degrading this kind of pollutants. However, mechanism mobilization hydrophobic compounds by non-motile microorganisms needs investigations improve pollutant bioavailability bioremediat...

Isolation of lignin degrading microorganisms from cow dung, soil compost, and paper pulp effluent was carried out in the present investigation. Totally 9 isolates of lignin degrading microbes were isolated using minimal salt media containing lignin (MSM-L) and lignolytic activities were preliminary screened by testing against methylene blue indicator dye containing LB medium. Eight microbes sho...

Finding an appropriate method with the highest rate of polycyclic aromatic hydrocarbon (PAH) removal from naturally polluted soils is important research issue. A pot factorial experiment (using contaminated soil samples Isfahan Refinery, Iran) was conducted in a 90-day period to compare following bioremediation strategies: (1) natural attenuation (NA): inherent ability for bioremediation; (2) b...
