Description
Pseudomonas fluorescens are Gram-negative rod shaped aerobic bacteria that inhabit soil, plants, and water surfaces. It is used as a bio-control agent against several plant disease causing pathogens. Pseudomonas fluorescens 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.
