Improvement of 1-OH-PHZ production. A HPLC chromatograms of fermentation broth of PH18-1 and PH18-1–8 at 250 nm. (i) Fermentation broth of PH18-1; (ii) Fermentation broth of PH18-1–8. 1, phenazine-1-carboxylic acid; 4, 1-hydroxyphenazine. B PH18-1–8 production of 1-hydroxyphenazine in different media. C The yield of PH18-1–8 1-hydroxyphenazine by adding different concentrations of shikimic acid to the medium. The data are from three experiment replicates, and are expressed as the mean value ± SD
