Di-(2-hydroxy-1-phenazinyl)methane, Phenazines, Bacterial Constituents, Pseudomonas aureofaciens The structure elucidation of di-(2- hydroxy-l-phenazinyl)methane from Pseudomonas aureofaciens is described. In addition to the phenazine derivatives isolated earlier from this bacterium 2,3,4-trihydroxyphenazine.

Transformation of phenazines in Pseudomonas aureofaciens were investigated with deuterated phenazine-1-carboxylic acid, 2-hydroxyphenazine-1-carboxylic acid, phenazine-1,6-dicarboxylic acid, methyl phenazine-1-carboxylate, dimethyl phenazine-1,6-dicarboxylate, and its mono methyl derivative. It was shown that hydroxylation and decarboxylation of phenazine-1-carboxylic acid gave rise to the variety of phenazines isolated from this strain.

ABSTRACT Two seven-gene phenazine biosynthetic loci were cloned fromPseudomonas aeruginosa PAO1. The operons, designatedphzA1B1C1D1E1F1G1 and phzA2B2C2D2E2F2G2, are homologous to previously studied phenazine biosynthetic operons from Pseudomonas fluorescens and Pseudomonas aureofaciens. Functional studies of phenazine-nonproducing strains of fluorescent pseudomonads indicated that each of the biosynthetic operons from P. aeruginosa is sufficient for production of a single compound, phenazine-1-carboxylic acid (PCA). Subsequent conversion of PCA to pyocyanin is mediated in P. aeruginosa by two novel phenazine-modifying genes,phzM and phzS, which encode putative phenazine-specific methyltransferase and flavin-containing monooxygenase, respectively. Expression of phzS alone inEscherichia coli or in enzymes, pyocyanin-nonproducingP. fluorescens resulted in conversion of PCA to 1-hydroxyphenazine. P. aeruginosa with insertionally inactivated phzM or phzS developed pyocyanin-deficient phenotypes. A third phenazine-modifying gene,phzH, which has a homologue in Pseudomonas chlororaphis, also was identified and was shown to control synthesis of phenazine-1-carboxamide from PCA in P. aeruginosa PAO1. Our results suggest that there is a complex pyocyanin biosynthetic pathway in P. aeruginosaconsisting of two core loci responsible for synthesis of PCA and three additional genes encoding unique enzymes involved in the conversion of PCA to pyocyanin, 1-hydroxyphenazine, and phenazine-1-carboxamide.

A description is given of a rare soil disease, called "barren ring", which occurs in some old, deserted pastures. It is an expanding ring-shaped area of diameter up to 17 meters in which the vegetation is killed. Regeneration of normal vegetation occurs in the center of the ring. A number of microorganisms were isolated from the barren soil and tested for phytotoxicity in vitro. Of 24 pure strains of bacteria and fungi isolated, only one bacterium showed phytotoxicity to the test organism, Phleum pratense L. It was identified as a strain of Pseudomonas aureofaciens Kluyver. Bioautography of extracts of the bacterial culture showed that there are two compounds extractable in benzene which have both antibiotic and phytotoxic activity. However, it has not been established that this bacterium is the sole causal agent of the disease and it is suggested that it is caused by an association of microorganisms.
