한국연안해역의 (韓國沿岸海域) 석유분해세균 분포에 관한 연구 = Abundance and distribution of petroleum - degrading bacteria in coastal waters of Korea

다국어 초록 (Multilingual Abstract)

Petroleum-degrading bacteria were enumerated from the coastal water near Samcheonpo City and Cheonsu Bay with the Most-Probable-Number method. Number of petroleum-degrading bacteria fluctuated from 2.0×10 exp (2) to 1.1×10 exp (5) cells/litre in the coastal water near Samcheonpo City, and 3.6×10 exp (1) to 1.1×10 exp (4) cells/litre in Cheonsu Bay. The proportions of petroleum-degrading bacteria to total viable counts were in the range of 2.1% to 0.00012%. In both study areas, ratio of petroleum-degrading bacteria at autumn showed the maximal value. Enterobacteriaceae, Vibrio, Bacillus, Pseudomonas, Flavobacterium, Acinetobacter, Micrococcus, Aerococcus and Aeromonas were isolated. Enterobacteriaceae, Vibrio and Pseudomonas were found dominantly. The observed results may be provided for understanding the level of potentiality of microbial petroleum-degradation in the research area.
