Biochem/physiol Actions

Gallium-pyoverdines act as growth inhibitors of both P. fluorescens and P. aeruginosa possibly due to gallium interference with bacterial iron metabolism.
Pyoverdines, also called pseuobactins and pyoverdins, are fluorescent siderophores that have high affinity for iron (1032 M-1), and are synthesized by fluorescent pseudomonads under iron-deficient growth conditions. Pyoverdines were shown to prevent iron toxicity produced by iron overload in hepatocyte cultures and effectively scavenges the hydroxyl and peroxyl radicals. Pyoverdines are effective in acquiring iron from transferrin and lactoferrin. Pyoverdines are also involved in the suppression of pythium-induced damping-off of tomato and promotion of growth in some higher plants.

Physical form

Supplied as a mixture containing mainly the succinic acid (MW=1231), 2-hydroxy glutaramide (MW=1260), and succinamide (MW=1230) forms of pyoverdines, bound to gallium.
