Characterization of a strain of Pseudomonas fluorescens that solubilizes phosphates in vitro and produces high antibiotic activity against several microorganisms

Abstract

The genus Pseudomonas is known as a P-solubilizer and antibiotic producer. In this work we have characterized a strain, PFBV1, which actively solubilizes phosphate in vitro and produces several antibiotics with high activity against several microorganisms. Using LMW RNA profile analysis we identified this strain as Pseudomonas fluorescens. Antimicrobial activity was detected against a wide spectrum of microorganisms, which included Gram negative bacteria such as Proteus vulgaris; Gram positive bacteria such as Bacillus subtilis and yeasts such as Candida albicans.
