I. Mechnikov National University», 2020.https://dspace.onu.edu.ua/handle/123456789/29118The aim of this work was to develop a method of obtaining siderophores and to study the influence of different cultivation conditions, in particular the composition of nutrient media, on the spectrum and level of their synthesis by some members of the Pseudomonas genus. Strains of Pseudomonas chlororaphis ONU 306, Pseudomonas fluorescens ATCC 13325 and Pseudomonas aeruginosa ATCC 10145 produced more intensely chelating compounds during cultivation in King B liquid medium. The corresponding values were higher than 9% for P. aeruginosa ATCC 10145) to 47% (for P. chlororaphis ONU 306). The spectrum of compounds of the siderophore series formed by the studied strains of pseudomonads mainly consisted of substances of hydroxamate and catechol type.ensiderophorespseudomonadsCAS-reagentnutrient mediumArticle
