TL;DR: In this article, a halothermophilic bacterial consortium capable of degrading polycyclic aromatic hydrocarbons (PAHs) in petroleum wastewater under extreme conditions was described.
57 citations
TL;DR: Results from MTBE biodegradation experiment show that the isolated bacteria were affected by propane, which indicates that propane may influence the metabolic pathway of MTBE by these bacteria.

TL;DR: In this article, the anaerobic metabolic processes in the degradation of explosives and nitroaromatic compounds under sulfate-reducing and methanogenic conditions were reviewed, and it was shown that sulfate reducing bacteria might metabolize nitroarsomatic compounds if appropriate electron donors and electron acceptors are present in the environment.

TL;DR: Microbial degradation of diesel fuel and lubricating oil was studied in artificial soils and predominantly alicyclic and branched-chain aliphatic organic acids as well as diacids and aromatic ketones were formed by degradation.

TL;DR: In this article, an efficient PAH (anthracene, phenanthrene, and pyrene)-degrading microbial consortium was isolated from a petrochemical sludge landfarming site.
Abstract: Anthracene, phenanthrene, and pyrene are polycyclic aromatic hydrocarbon (PAHs) that display both mutagenic and carcinogenic properties. They are recalcitrant to microbial degradation in soil and water due to their complex molecular structure and low solubility in water. This study presents the characterization of an efficient PAH (anthracene, phenanthrene, and pyrene)-degrading microbial consortium, isolated from a petrochemical sludge landfarming site. Soil samples collected at the landfarming area were used as inoculum in Warburg flasks containing soil spiked with 250 mg kg−1 of anthracene. The soil sample with the highest production of CO2-C in 176 days was used in liquid mineral medium for further enrichment of anthracene degraders. The microbial consortium degraded 48%, 67%, and 22% of the anthracene, phenanthrene, and pyrene in the mineral medium, respectively, after 30 days of incubation. Six bacteria, identified by 16S rRNA sequencing as Mycobacterium fortuitum, Bacillus cereus, Microbac...
