Abstract
An experiment was planned to evaluate the behavior of Paenibacillus polymyxa SQR-21 under differential iron availability. P. polymyxa was grown under three differential iron conditions (0, 2, 20 μM). Iron starvation slowed bacterial growth and at all iron levels, pH of liquid culture was decreased, but maximum decrease was observed at highest iron level. Cell surface ferrireductase activity decreased as culture aged, while extracellular Fe3+-reducing activity constantly increased. Hydroxamates type siderophores production was increased with the decrease in iron levels. Numerous cellular proteins were expressed by P. polymyxa in the range of 5–140 kDa and several of them showed conspicuous differential iron regulation. P. polymyxa seems to have more than one type of iron acquisition mechanism including gradual release of organic acids, cell surface ferrireductases, extracellular reductants, and secretion of low molecular weight hydroxamates chelators. This article is the first to report the kinetic study of P. polymyxa under differential iron availability. The information provided here gives initial information about the iron uptake mechanism of P. polymyxa.
