Dimer Of Phenazine-1-Carboxylic Acid And To The Process Of Preparation Thereof

Abstract

A dimer of phenazine-I-carboyxlic acid natural products from fluorescent pseudomonad bacterium and a method of preparing a dimer of phenazine-I-carboxylic acid natural product are disclosed herein. The method comprises growing the bacterium in a water based liquid medium under favorable pH and temperature with continuous agitation, extracting the dimer of phenazine-I-carboyxlic acid natural product from the medium by centrifugation using organic solvents, filtering the resultant emulsion to separate the aqueous layer in a separation funnel, isolating the crude dimer of phenazine-I-carboyxlic acid natural product from the organic layer by evaporating the organic solvent, and purifying the dimer of phenazine-I-carboxylic acid natural product by chromatography.
