Identification and Quantification of Secondary Metabolites by LC-MS from Plant-associated Pseudomonas aurantiaca and Pseudomonas chlororaphis.

ABSTRACT: Increased antibiotic resistance of plants and human pathogens and continuous use of chemical fertilizers has pushed microbiologists to explore new microbial sources as potential antagonists. In this study, eight strains of Pseudomonas aurantiaca and Pseudomonas chlororaphis, have been isolated from different plant sources and screened for their antagonistic and plant growth promoting potential ( Shahid et al., 2017 ). All strains were compared with reference strain PB-St2 and their secondary metabolites were isolated by the use of solvent partitioning and subjected to LC/ESI/MS for confirmation of compounds. The ESI-mass spectra obtained were used to characterize the surfactants ionization behavior and [M + H]⁺ and [M + Na]⁺ ions were monitored fo
