Abstract
The effect of different organic compounds (glucose, fructose, ribose, glycine, alanine, pyruvate, acetate, citrate, and yeast extract) as well as of the wastes of food production (molasses, stillage, sweet whey), on the growth of iron-oxidizing acidophilic microorganisms and biooxidation of ferrous iron was studied. Representatives of the microorganisms predominating in biohydrometallurgical processes—archaea of the family Ferroplasmaceae (A. aeolicum V1T, A. cupricumulans BH2T, Acidiplasma sp. MBA-1, Ferroplasma acidiphilum B-1) and bacteria of the genus Sulfobacillus (S. thermosulfidooxidans SH 10–1, S. thermotolerans Kr1T)—were the subjects of the study. All studied strains most actively grew and oxidized ferrous iron in the presence of yeast extract, which is probably due to the presence of a large number of different growth factors in its composition, while others substrates provided growth of microorganisms and ferrous iron oxidation.
