Abstract
Experimental investigation on the iron impact upon some bacteria growth was carried out aiming to compare the effects of
various sources of iron ions. Turbidimetric assay of the cell density in P. aeruginosa liquid culture media following the
addition of iron aliquots delivered by iron salts and oxides was performed to get quantitative information on this human
pathogen sensitivity to ferric and ferrous ions. The feature of iron scavenger of P. aeruginosa was revealed as resulted from
the stimulatory influence of relatively low iron concentrations, for magnetite and ferrous sulfate while nonsignificant uptaken
of iron from ferric chloride was found.
Keywords
