Pseudomonas fluorescens is a common Gram-negativerod-shaped bacterium.

It has an extremely versatile metabolismand can be found in the soil and in water. It is an obligate aerobebut certain strains are capable of using nitrate instead of oxygen as a final electron acceptor during cellular respiration. Optimal temperatures for growth of P. It tests positive for the oxidase test. It is also a nonsaccharolytic bacterial species.

Heat -stable lipases and proteases are produced by P. The word was used early in the history of microbiology to refer to germs. The specific name fluorescens fluorescenw to the microbe’s secretion of a soluble fluorescent pigment called pyoverdinwhich is a type of siderophore. The genomes of P.

Pseudomonas fluorescens – Wikipedia

There are two strains of Pseudomonas fluorescens associated with Dictyostelium discoideum. One strain serves as a food source and the other strain does not.

The main genetic difference between these two strains is a mutation of the global activator gene called gacA. This gene plays a key role in gene regulation; when bskteri gene is mutated in the nonfood bacterial strain, it is transformed into a food bacterial strain. It is not clear exactly how the plant growth-promoting properties of P.

To be specific, certain P. PhlD shows similarity to plant chalcone synthases and has been theorized to originate from horizontal gene transfer.

Some experimental evidence supports all of these theories, in certain conditions; a good review of the topic is written by Haas and Defago. Several strains of P. The strain referred to as Pf-CLA has proved itself a promising solution for the control of invasive zebra mussels and quagga mussels Dreissena. Recent results showed the production of the phytohormone cytokinin by P.

From toan outbreak of P. The source of the infection was contaminated heparinized saline flushes being used with cancer patients.
