Intrinsic Anaerobic Bioremediation of Hydrocarbons in Contaminated Marine Sediments.

摘要

Microbial cultures, capable of anaerobic hydrocarbon degradation were obtained from the anaerobic marine sediments in San Diego Bay (Paleta Creek sediments) Using n-alkanes (from C6 to C12), alkyl-benzenes (toluene, ethylbenzene, 0-, m-, and p-xylene isomers), and alkyl-cycloalkanes (ethyl cyclopentane), in conjunction with C13 nuclear magnetic resonance spectroscopy and gas chromatography-mass spectrometry (some of the hydrocarbon compounds were labeled with either 2H and C13-nuclei), anaerobic biodegradation reaction pathways and metabolite structures were identified and characterized.
