AbstractHydrocarbon-degrading bacteria were isolated by enrichment culture from littoral sediments and seawater collected in Narragansett Bay during the winter of 1971-72. Enrichment substrates were distillate residual fuel oils and kerosene. Representative isolates were screened on n-hexadecane, methylcyclohexane, p-xylene, n-hexylbenzene and naphthalene to demonstrate their ability to grow at the expense of a range of hydrocarbons on solid media at 0, 8, 16 and 24.degree. C. Growth on the candidate hydrocarbons at all 4 incubation temperatures indicated that the bacteria were facultative psychrophiles. The rate of growth at 10.degree. and 20.degree. C was determined for 2 hydrocarbon-degrading bacteria grown on n-dodecane and naphthalene in liquid culture. The average generation time was 11.0 and 5.9 h at 10.degree. and 20.degree. C, respectively.
