In this study the biodegradation of oil by hydrocarbon degrading Pseudomonas putida in the presence of a biosurfactant-producing bacterium was investigated. The co-culture of test organisms exhibited improved degradation capacities, in a reproducible fashion, in aqueous and soil matrix in comparison to the individual bacterium culture. Results indicate that the in situ biosurfactant production ...

Biodegradation of crude oil in subsurface petroleum reservoirs has adversely impacted most of the world's oil, converting this resource to heavier forms that are of lower quality and more challenging to recover. Oil degradation in deep reservoir environments has been attributed to methanogenesis over geological time, yet our understanding of the processes and organisms mediating oil transformat...

Petroleum-based products are the major source of energy for industry and daily life. Petroleum is also the raw material for many chemical products such as plastics, paints, and cosmetics. The transport of petroleum across the world is frequent, and the amounts of petroleum stocks in developed countries are enormous. Consequently, the potential for oil spills is significant, and research on the ...

Alkyl polyglucosides, due to their low toxicity and environmental compatibility, could be used in biodegradation of hydrophobic compounds. In this study, the influence of Lutensol GD 70 on the cell hydrophobicity and zeta potential was measured. The particle size distribution and surfactant biodegradation were also investigated. Microbacterium sp. strain E19, Pseudomonas stutzeri strain 9, and ...

Material efficiency is nowadays an essential topic to promote the sustainable use of natural resources, waste materials and industrial by-products, in agreement with the principle of sustainable development and LCA (life cycle assessment). In this research it was determined the biodegradation of used vegetable oil based products and their important physicochemical properties for their suitabili...

The environment is considered as man’s important asset that must be protected for his life support. Regrettably the situation is different where oil refinery and petrochemical plants operate. Environmental pollution in the form of emissions and effluent discharge in these area poses serious threat to the ecosystem particularly soil, often with undesirable effects. The study collected soil sampl...

background: much of the environment is affected by petroleum contamination. it imposes serious health problems for humans as well as serious environmental impact. bioremediation is an important consideration for removing environmental pollutants because, compared with other technologies, it incurrs lower costs and is environmentally compatible. methods: crude oil degrading bacteria were isolate...

Polycyclic aromatic hydrocarbons (PAHs) are classified as hazardous pollutants in the environment due to their toxic, mutagenic and recalcitrant nature. Compared to other methods, biodegradation using microorganisms seems to be attractive alternative for treating PAH contaminated environment. However, there are limitations because of its low aqueous solubility and negligible bioavailability to ...
