Microorganisms that degrade heavy oil C (HOC) were screened by enrichment in alumina columns containing HOC and a slowreleasing fertilizer. The alumina columns were immersed in a bath in which natural sea water was periodically ebbed and flowed through a siphon. After two months of enrichment, 153 HOC degraders were isolated from the cultures, and three of them were demonstrated to degrade about 50% of HOC at 30℃ for l0 days. A taxonomic examination of these three strains indicated that two of them belonged to the genus Rhodococcus while the third the genus Agrobacterium. The degradability of these strains was 1.7 to 4.8 times higher than that of other known oil-degrading microorganisms.
