Microbial methanogenesis in subsurface oil and coal
Research in Microbiology, 2013It is now clear that active methanogens are present in the deep-subsurface. This paper reviews microbial population structures and the biodegradation of organic compounds to methane in situ within oil reservoirs and coal deposits. It summarizes our current knowledge of methanogenes and methanogenesis, fermenters, synthrophs and microbial metabolism of ...

Microbial communities in oil-contaminated seawater
Current Opinion in Biotechnology, 2004Although diverse bacteria capable of degrading petroleum hydrocarbons have been isolated and characterized, the vast majority of hydrocarbon-degrading bacteria, including anaerobes, could remain undiscovered, as a large fraction of bacteria inhabiting marine environments are uncultivable.

Microbial desulphurization of heavy oils and bitumen
Biotechnology Advances, 1987Most oil producing countries have extensive reserves of heavy oil and bitumen. As easily accessible sources of conventional crudes decline, these reserves will become more important in supplementing the energy requirements. Heavy oil and bitumen are highly viscous and contain 3 to 6% sulphur.

Marine Pollution Bulletin, 1972
Abstract It is generally assumed that bacteria in the sea can degrade almost anything they are offered, and it is widely believed that petroleum oil is entirely biodegradable. This underlies present policies of dispersing polluting oil. There is good reason to suppose that this faith is not well founded and a good deal more will need to be known ...

Simulation of Microbial Enhanced Oil Recovery
International Oil Conference and Exhibition in Mexico, 2006Abstract Nowadays, the experts in biotechnology and oil engineering cooperate to improve the production of oil reservoirs. A large portion of the world energy consists of non-renewable fossilized fuels; the primitive methods in oil recovery just make 8 to 30 percent of oil reservoirs available.

Microbial enhanced oil recovery (MEOR)
Current Opinion in Microbiology, 2010Two-thirds of the oil ever found is still in the ground even after primary and secondary production. Microbial enhanced oil recovery (MEOR) is one of the tertiary methods purported to increase oil recovery. Since 1946 more than 400 patents on MEOR have been issued, but none has gained acceptance by the oil industry.

Biotechnological production of oil: Fatty acid composition of microbial oil
Plant Foods for Human Nutrition, 1999The fatty acid profile and the fatty acid composition of microbial lipids obtained from molds revealed that oil from Aspergillus sydowii, Fusarium oxysporum and F. equisetti had a high percentage of unsaturated fatty acids, particularly oleic acid, and had a similarity to the edible oils, groundnut and palm oil.

Microbial Potential for Cleaning the Oiled Iron Scale
Прикладная биохимия и микробиология, 2014The possibility of using microorganisms to clean oiled iron scale of metallurgical production was investigated with the goal of recuperation. A stable microbial association growing on mineral oil as the sole carbon source was isolated from a sample from oiled iron scale taken directly from a metallurgical plant.

Microbial Surfactants: Alternative to Vegetable Oil Surfactants
2019Biosurfactants, surface active molecules synthesized by microorganisms, represent a promising alternative to the synthetic surfactants in many different applications. Among them, rhamnolipids have attracted considerable attention in the last years due to their extraordinary surface-active properties and biological activities.
