Hydrocarbon utilizing bacteria were isolated from several low temperature water and sediments and were found to represent 15 different genera. All isolated were psychrotolerant and had Q10 values ranging from 1.3-2.4 and metabolized representative aromatic, naphthenic and aliphatic hydrocarbons. In situ degradation rates were demonstrated to be much lower than laboratory rates and were on the order of magnitude of ngs of substrate per day. The sediment microbial populations in an oiled beach were shown to select for hydrocarbon metabolizing organisms and this selection correlated with degradation of hydrocarbons in the sediments. Hydrocarbon metabolizing microorganisms contain inclusions not present in the same organisms grown on peptone. The inclusions are identified as hydrocarbon oxidation products and are hot pooled hydrocarbon. Author
