The Nakhodka, a Russian tanker loaded with C-typed heavy oil of 19,000 kl was divided into sections and submerged off Oki Island, Shimane Prefecture on January 2,1997. The bow, after being drifting for 4 days, was wrecked off Anto, Mikuni town, Fukui Prefecture, threatened throughout the various shores of Ishikawa Prefecture geographically as well. Shore damage by oil washing was observed by aerial research of K. Tazaki, as of 8 Feb. 1997. An oil layer at the shore of Mikuni Town reached over 50 cm in thickness. We conducted field surveys in order to examine the conditions of heavy oil washing ashore on the Ishikawa coastline, in this accident, remarkable microbial remediation research had been advanced. In fact, hydrocarbon-degrading microbes were found in each polluted area of the near-shore environments. Hydrocarbon-utilizing bacteria isolated from coastal areas. Local degrader bacteria inhibited everywhere with many kinds of species. Each species carries a role ta resolve heavy oil under the local conditions. That is a key to understand the sustainable "bioremediation " for polluted local area. After 5 years of spilled accident, degrader bacteria were still alive to keep the activity.

1997年1月2日，俄罗斯“纳霍德卡”号油轮在岛根县隐岐岛附近海域被分成若干部分沉没。船头在漂流了4天后，在福井县三国镇安东附近失事，在地理上也威胁到了石川县的各个海岸。通过对K.田崎，1997年2月8日。三国町海岸的油层厚度超过50厘米。为了考察石川沿岸的重油冲上岸情况，我们进行了现场调查，在这次事故中，开展了显著的微生物修复研究。事实上，在近岸环境的每个污染区都发现了降解碳氢化合物的微生物。从沿海地区分离的碳氢化合物利用细菌。本地降解菌种类繁多，处处受抑制。在当地条件下，每种矿物都具有一定的稠油溶解作用。这是理解污染区域可持续“生物修复”的关键。泄漏事故发生5年后，降解菌仍然存活并保持活性。
