Abstract The structure elucidation of several minor phenazine pigments of Pseudomonads is described. 4-Hydroxyphenazine-1,6-dicarboxylic acid dimethyl ester, 2,3-dihydroxyphenazine, 2,3,7-trihydroxyphenazine, 4-hydroxyphenazine-1-carboxylic acid, 2,3-dihydroxyphenazine-1-carboxylic acid, 2,6-dihydroxyphenazine-1-carboxylic acid and 2,3,7-trihydroxyphenazine-1,6-dicarboxylic acid are new phenazine derivatives. The distribution of phenazines in the genus Pseudomonas is investigated.

In addition to phenazine, phenazine-1-carboxylic acid, phenazine-1,6-dicarboxylic acid and 2,9-dihydroxyphenazine-1-carboxylic acid a new compound, viz. 2,3,9-trihydroxyphenazine-1-carboxylic acid could be isolated from the culture medium of Pseudomonas fluorescens grown under iron deficiency with beryllium added to the culture medium. Its structure elucidation is described.
