Profiling of antimicrobial metabolites of plant growth promoting Pseudomonas spp. isolated from different plant hosts.

ABSTRACT: In this study, nine strains of Pseudomonas au rantiaca and P. chlororaphis, and two isolates of Pseudomonas sp.: At1RP4 and RS-1, were characterized for the in-vitro production of secondary metabolites in LB, DMB, and King's B media, and of the genes responsible for the production of antagonistic metabolites. Based on 16S rRNA gene sequence, isolates At1RP4 and RS-1 were identified as strains of P. aeruginosa and P. fluorescens. Five phenazine derivatives comprising phenazine, phenazine-1-carboxylic acid (PCA), 2-hydroxyphenazine-1-carboxylic acid (2-OH-Phz-1-COOH), phenazine-1,6-dicarboxylic acid (Phz-1,6-di-COOH), and 2-hydroxyphenazine (2-OH-Phz) were produced by all strains in all three culture media including DMB, King's B and LB.
