using environmental-friendly methods in order to remove or reduce oil pollutants and their derivations in the environment are developing. in this study, the biodegrading ability of bacillus subtilis .sp which has been separated from oil-polluted soil was examined. it was revealed that it can reduce surface tension of growth medium and produce bio-surfactant at 37 and 20 degrees centigrade. also...

Chlorpyrifos-methyl (CM) is a broad-spectrum organophosphate insecticide, which widely used in pest control. In this research, the isolation, and biochemical molecular identification of bacterial strains obtained from three soils located northeastern Algeria were carried out, as well evaluation their ability to grow presence CM. Out 48 isolates between Gram-negative Gram-positive identified, se...

Increase of plastics accumulation in the environment cause ecological threats and has been one serious issue worldwide. In current study, two bacterial isolated strains Bacillus safensis amyloliquefaciens were used for their plastic degradation capabilities. The biodegradation low density polyethylene thermoplastic was assessed by weight reduction, Scanning electron microscopy (SEM) analysis cu...

Deoxynivalenol (DON) is a mycotoxin mainly produced by Fusarium graminearum and culmorum commonly found in cereals such as wheat, barley, oats, their derivatives. Scientists have been working on different strategies for DON detoxification, with biological detoxification being an approach growing interest. When evaluating the use of microorganisms phenomena can occur, namely, biotransformation (...

The microbial ecology of any biodegradation system is the fundamental factor that controls both the effectiveness of the ongoing biodegradation process and also the ability of the biodegrading population to maintain stability at times of environmental stress. Studies are reported here which provide both initial information on the ecology of an oil degrading porous pavement system (PPS) and sign...

Petroleum hydrocarbon-degrading fungi were isolated from Detarium senegalense seeds. An assessment of the relative ability of each fungus to degrade petroleum crude oil, diesel, unspent and spent engine oils, kerosene and Detarium senegalense oil extract, on minimal salt broth, was done measuring change in optical density read on a spectrophotometer. Five fungi were isolated from diseased namel...
