ABSTRACT


A soil strain of Pseudomonas putida intensively
secreted, under iron deficiency conditions, a single form of siderophore-pyoverdine
to the medium. The siderophore was isolated from the culture medium and purified
using chelating chromatography. Purified pyoverdine inhibited the growth of all
studied Fusarium strains except for F. graminearum. The presence
of pyoverdine stimulated the growth of some of the tested strains. Based on MS
spectrum analysis it can be concluded that Pseudomonas putida produced
a pyoverdine with low molecular mass of 800 Da.

Key words: siderophore, pyoverdine, Pseudomonas, biocontrol.
