title: Identification of NRRL strain B-18602 (PR3) as Pseudomonas aeruginosa and effect of phenazine 1-carboxylic acid formation on 7,10-dihydroxy-8(E)-octadecenoic acid accumulation.
abstract: A new compound, 7,10-dihydroxy-8(E)-octadecenoic acid (DOD), produced from oleic acid by a new bacterial isolate PR3, was discovered in 1991. We have now identified isolate PR3 as a strain of Pseudomonas aeruginosa by DNA reassociation studies. Strain PR3 also produced a crystalline yellowish compound the structure of which, as determined by GC/MS and NMR, is phenazine 1-carboxylic acid (PCA). In cultures of PR3, high PCA production was associated with low DOD accumulation.
