摘要: Exopolysaccharides (EPS) producing Pseudomonas aeruginosa PF23EPS+ and its mutant PF23EPS− (EPS deficient strain) taken from authors collection were monitored for salicylic acid (SA) production. Strain displayed SA production biocontrol against phytopathogen Macrophomina phaseolina up to 500 mM NaCl. However, was defective in EPS significant reduction under non-stress conditions. The neither nor at diverse salt concentrations, authenticating the relation of antagonism. Pot field trials conducted salinized soil infested with M. taking sunflower as test crop. Results study agreement findings pot study. combination strain extracted obtained it brought enhancement plant growth parameters disease incidence saline reports application promoting (PGP) microbe P. PF23 metabolite enhancing crop phaseolina.
