This Gram-negative bacterium inhabits soil, plants and water surfaces (micro wiki 2). Some strains of this bacterium reside in the rhizosphere of plants where they are capable of producing secondary metabolites, including antibiotics against certain plant pathogens present in the soil (Ganeshan 123). Pseudomonas fluorescens shares a commensal relationship with the plant on which it lives. The bacteria receive nutrients and environmental protection from plants, and in turn the microorganism provides essential nutrients, degrades pollutants, and produces antibiotics that protect against plant pathogens (Ganeshan 124). Currently, research is underway to assess the significance of the microbe's ability to be used as an alternative to synthetic pesticides (micro wiki 2). Pseudomonas fluorescens is toxic to the larvae and pupae of mosquito vectors, and has the ability to produce antibiotics and hydrogen cyanide that can kill other microbes, including Ganeshan fungi 124). Although this microbe has the potential to have a positive impact on agriculture and the agricultural industry, Pseudomonas fluorescens also has a positive effect on humans.
