Pseudomonas fluorescens has multiple flagella.
It has an extremely versatile metabolism, and can be found in the
soil and in water. It is an obligate aerobe, but certain strains
are capable of using nitrate instead of oxygen as a final electron
acceptor during cellular respiration.
Optimal temperatures for growth of Pseudomonas
fluorescens are ****0 degrees Celsius. It tests positive for the
oxidase test. Pseudomonas fluorescens is also a nonsaccharolytic
bacteria.
Heat-stable lipases and proteases are produced
by Pseudomonas fluorescens and other similar pseudomonads. These
enzymes cause milk to spoil, by causing bitterness, casein
breakdown, and ropiness due to production of slime and coagulation
of proteins.
Applications: Seed treatment Seedling Root dip Soil application Used as a bio-control agent against
several plant disease causing pathogens. Produces a soluble, green fluorescent pigment
pyoverdine which is responsible for chelating iron only when
concentrations are low. Pseudomonas fluorescens are commensal species
with plants, allowing plants to attain key nutrients, degrading
pollutants, and suppressing pathogens via antibiotic
productions.
Specifications: Microbial Count: **0
million/mL
Competitive
Advantage: Enhance ecological performance in the
rhizosphere It can better resist attack by a true
pathogen Produce compounds antagonistic to other soil
microbes Approved for use in organic
agriculture. Non-chemical and non-toxic. Suitable for organic farming. Does not lead to residue
problems Doesn’t cause resistance or resurgence
problems.
