| Abstract |
A total of 96 strains of petroleum-degrading bacteria isolated from the Nakdong River Estuary by liquid-enrichment method. isolated strains were confirmed as petroleum-degrading bacteria and characterized using numerical taxonomy. The isolates were examined for 54 biochemical, cultural, morphological, and physiological characters. The data were analyzed by computer, using simple matching coefficients and clustering was achieved by the average linkage method. From the dendrogram, 10 phenetic groups were defined at the 75% similarity level. Identified groups were Aeromonas, Enterobacteriaceae, Flavobacterium, Lucibacterium, Pseudomonas, and Vibrio with Enterobacteriaceae as dominants. It was concluded that degradation of petroleum in the estuarine environment was accomplished by indigenous bacteria of numerous genera and high proportion of the phenetic groups were specific to the environmental conditions of sampling sites. |
