  • Two kinds of crude oil-degrading microorganisms from soil and one kind from sea were isolated and named strain Al32, strain F722 and strain OM1, respectively. These microorganism were identified Acinetobacter sp., Pseudomonas aeruginosa and Acinetobacter calcoaceticus, respectively. The optimum cultivation temperature of Acinetobacter sp. A132 and P. aeruginosa F722 was $35^{\circ}C$ and optimum growth pH was 8 and 9, respectively. The growth was the highest at 2.0% (w/v) substrate concentration when crude oil was only carbon source. The growth of A. calcoaceticus OM1 isolated from sea was the highest at 3.0% (w/v) of crude oil. In inspection of crude oil degradability, strain Al32 showed 5.49 g/L.day with Eleuthera (OMAN), 2.0% (w/v). P. aeruginosa F722 showed 1.19 g/L g/L.day with L-Zakum (AFRICA). In case of kerosene $nC_9\simnC_{20}$ and diesel $nC_9\simnC_{28}$, A. calcoaceticus OM1 was degraded 95% and 75%, respectively, for 7 days culture, and P. aeruginosa F722 was 80% after 10 days.
