I. Mechnikov National University», 2020.https://dspace.onu.edu.ua/handle/123456789/29109At present time phenazine compounds produced by Pseudomonas bacteria are applied in many industries. These substances are used in the biotechnology, including agricultural production. The aim of this work was to study the effect of the nutrient composition on the intensity of accumulation of phenazine compounds by pseudomonad cultures. The dependence of the intensity of accumulation of phenazine antibiotics on the composition of the nutrient medium, in particularly the presence of metal cations in it was detected. It can be assumed that the phenazine derivative synthesis is strain specific process. It was also noted that the intensity of the production of these compounds did not correspond to the rate of cell biomass accumulation by the studied Pseudomonas strains.enphenazine compoundsPseudomonas strainsmicrobial cell biomassnutrient medium compositionArticle
