Phenazine synthesis

WebIn addition to E. coli, the core phenazine biosynthesis genes have also been introduced into P. putida strains (Figure 4b). In 2015, Rosenbaum and co-workers engineered the phenazine biosynthetic pathway from P. aeruginosa PAO1 into P. putida KT2440 cells, which produced phenazine-1-carboxylic acid as the dominant redox mediator 62a. Classically phenazine are prepared by the reaction of nitrobenzene and aniline in the Wohl-Aue reaction. Other methods include: • pyrolysis of the barium salt of azobenzoate • oxidation of aniline with lead oxide • oxidation of dihydrophenazine, which is prepared by heating pyrocatechin with o-phenylenediamine.
