Screening of phosporus solubilizing bacteria Pseudomonas spp. growth activity in dependence on glyphosate content in liquid Dworkin-Foster medium

Abstract

Screening of 15 strains of phosphorus solubilizing rhizobacteria Pseudomonas spр. by cultivation in liquid Dworkin-Foster medium with glyphosate as phosphorus source showed common dependence of bacteria growth on concentration of glyphosate. High population density was observed in diapason of 0,20–0,60 µкг of glyphosate per ml of medium, the increase of glyphosate concentration resulted in the significant reduction of population densities. Screening showed that phosphorus solubilizing rhizobacteria Pseudomonas sрp. virtually not capable of glyphosate utilization as a sole nitrogen source for metabolism.
