摘要
Rhodococcus erythropolis DCL14 cells were able to metabolise C5-C16 hydrocarbons and C1-C12 alcohols as sole carbon and energy sources, both at 15 and 28 degreesC. Metabolic activity was also observed at 1.00%, 1.95% and 2.50% sodium chloride. Almost complete degradation of n-, iso- and cyclo-alkanes and aromatic compounds present in fuel oil was achieved after 9 months, 60% being consumed in the first three months. The results from the conditions tested here suggest that this type of bacterium could be involved in bioremediation processes in marine environments such as the Atlantic, Pacific and Indian Ocean.
