Identification of Pseudomonas aeruginosa Using Fatty Acid Analysis

Cellular fatty acid composition of 17 strains of the Pseudomonas aeruginosa was determined by gas-liquid chromatography isolated from environmental and clinical sample in a C university hospital. Straight-chain saturated acid of C16:0 and straight-chain unsaturated acid of C18:1 with a double bond were commonly found in all the strains tested. The presence of 12:0 3OH (3-10%), 16:0 (18-28%), and 18:1w7c (17-37%) showed the characteristics of the species in the Pseudomonas. Bacterial fatty acid composition was considered to be useful for the study of interrelation and for rapid identification of the bacteria.
