Document Summary
Pseudomonas aeruginosa is motile by means of a single polar flagellum. P. aeruginosa can live in a sessile biofilm form, or it can live in a planktonic form, as a free-swimming cell. The pseudomonads have great practical impact in several ways: many can degrade an exceptionally wide variety of organic molecules. Important in breakdown of organic materials (mineralization process) in nature and sewage. 80 different substances as carbon and energy sources! Large number of genes for catabolism, nutrient transport, the efflux of organic molecules and metabolic regulation. Genome (6. 3 million base pairs) more complex than e. coli. Pseudomonas- an easy microbe to identify: gram negative rod, motile, aerobic, prototroph, no special growth requirement, oxidase positive --the oxidase test is one of the most useful and common test used to differentiate groups of micro-organims. This bacteria cause"s skin infections, urinary tract infections and septicemia.
