Biodegradation is an economical and efficacious option to purification among purifying methods. Capable PAHs degrading microorganisms are common in sediments contaminated by these compounds. Purifying ability enhance with biosurfactant production by microorganisms. Hence in this research after isolation and identification of two antheracen resistant bacteria, Pesudomonas aeruginosa and Pesudomo...

Bioremediation refers to the use of organisms to remove environmental pollutants. Besides identifying different new plasmids capable of degrading environmental pollutants, many attempts have been taken by the genetic engineers to enhance the bioremediation potential of different microorganisms. Escherichia coli was engineered to convert chlorinated solvents such as trichloro ethylene and the hi...
Oil in subsurface reservoirs is biodegraded by resident microbial communities. Water-mediated, anaerobic conversion of hydrocarbons to methane and CO2, catalyzed by syntrophic bacteria and methanogenic archaea, is thought to be one of the dominant processes. We compared 160 microbial community compositions in ten hydrocarbon resource environments (HREs) and sequenced twelve metagenomes to chara...
BACKGROUND The use of microorganisms in remediating environmental contaminants such as crude oil sludge has become a promising technique owing to its economy and the fact it is environmentally friendly. Polycyclic aromatic hydrocarbons (PAHs), as the major components of oil sludge, are hydrophobic and recalcitrant. An important way of enhancing the rate of PAH desorption is to compost crude oil...
background: the presence of chemical compounds has different effects on the rate of degradation of materials and on changing dominant microorganisms in the biological degradation processes. these effects are related to the type and concentration of compounds. this study was to evaluate the effect of different concentrations of glucose as a growth substrate on phenol removal efficiency and micro...
The fate of hydrocarbon pollutants and the development of oil-degrading indigenous marine bacteria in contaminated sediments are strongly influenced by abiotic factors such as temperature, low oxygen levels, and nutrient availability. In this work, the effects of different biodegradation processes (bioremediation) on oil-polluted anoxic sediments were analyzed. In particular, as a potential bio...
Petroleum refining industries produce large amounts of toxic effluents, causing environmental pollution. Iran is an oil-rich country that encounters oil pollution in its soil and water. Bioremediation of these pollutants is an appropriate solution to tackle them, compared to physical and chemical remediation methods. There are some factors that increase the rate of biodegradation; therefore, th...
Weathering processes change properties and composition of spilled oil, representing the main reason of failure of bioaugmentation strategies. Our purpose was to investigate the metabolic adaptation of hydrocarbon-degrading bacteria at harsh conditions to be considered to overcome the limitations of bioaugmentation strategies at harsh conditions. Polluted soils, exposed for prolonged periods to ...
