Abstract
To find the applicability of resemblance of the fatty acid methy1 ester (FAME) profile analysis to the primary examination for the tracing P. aeruginosa contamination in the environment and water plants, we designed this study. Of6l P. aeruginosa isolates including 3 reference strains, 4 fecal or soil isolates and 54 water isolates, the resemblance coefficiencies of the FAMEs were calculated as euclidian distance (ED) and expressed as dendrogram. The 61 strains were clustered as the same group in the ED 8.4, and divided into 4 subgroups in the ED 6.9. The water isolates from Han River were classified into distinctively different subgroups from reference strains. These results provide the possibility of the dendrogram from FAME profile as a useful tools for tracing contamination as well as for identifying the species, especially in case of P. aeruginosa.
