Fluviols, bicyclic nitrogen-rich antibiotics produced by Pseudomonas fluorescens

Fifteen fluorescent pseudomonads, isolated from the rhizosphere of agricultural plants, were similar in both their phenotypic properties and the chemical nature of produced pigments, to the previously described Pseudomonas fluorescens var. pseudoiodinum. DNA-DNA hybridisation data showed their genet...

Description
Summary:Fifteen fluorescent pseudomonads, isolated from the rhizosphere of agricultural plants, were similar in both their phenotypic properties and the chemical nature of produced pigments, to the previously described Pseudomonas fluorescens var. pseudoiodinum. DNA-DNA hybridisation data showed their genetic similarity (but not identity) to different biovars of P. fluorescens. A family of antibiotics-fluviols belonging to pyrazolo-[4,3-e]as-triazine derivatives was isolated from studied strains; isolation, properties, antimicrobial and antitumour activity of fluviols are described.
