Anaerobic biodegradation of n-hexadecane by a nitrate-reducing consortium.
Nitrate-reducing enrichments, amended with n-hexadecane, were established with petroleum-contaminated sediment from Onondaga Lake. Cultures were serially diluted to yield a sediment-free consortium. Clone libraries and denaturing gradient gel electrophoresis analysis of 16S rRNA gene community PCR products indicated the presence of uncultured alpha- and betaproteobacteria similar to those detec...
متن کاملbiodegradation of n-hexadecane in acinetobacter radioresistens liquid culture
background diesel oil hydrocarbons are the most common contaminants of our biological environment. considering the fact that iran is one of the major producers of diesel oil products, it greatly contributes to soil and water pollution. currently, soil and water pollutions caused by diesel oil products leakage, from distribution stations, is one of the major concerns in iran. based on the studie...
متن کاملBiodegradation of linear alkylbenzene sulfonate by a two-member facultative anaerobic bacterial consortium
A bacterial consortium capable of degrading the linear alkylbenzene sulfonate (LAS) was isolated from the wastewater treatment plant. The bacterial consortium consisted of two members, Pantoea agglomerans and Serratia odorifera 2. Cells were grown evenly together in a minimal medium (M9) and nutrient broth (NB). The bacterial consortium was able to grow in the minimal medium containing LAS as t...
متن کاملAnaerobic degradation of oil hydrocarbons by sulfate-reducing and nitrate-reducing bacteria
Crude oil is a complex mixture mainly composed of various saturated and aromatic hydrocarbons. Whereas degradation of hydrocarbons by oxygen-respiring microorganisms has been known for nearly one century, utilization of hydrocarbons under anoxic conditions has been investigated only during the past ten years. The present paper summarizes investigations into the anaerobic degradability of crude ...
متن کاملDegradation of n-hexadecane and its metabolites by Pseudomonas aeruginosa under microaerobic and anaerobic denitrifying conditions.
A strategy for sequential hydrocarbon bioremediation is proposed. The initial O(2)-requiring transformation is effected by aerobic resting cells, thus avoiding a high oxygen demand. The oxygenated metabolites can then be degraded even under anaerobic conditions when supplemented with a highly water-soluble alternative electron acceptor, such as nitrate. To develop the new strategy, some phenome...
