Influence of Colloidal Iron on the Respiration of a Species of the Genus Acinetobacter

By I. C. Mac Rae and Jovenia S. Celo

Abstract

Washed suspensions of Acinetobacter sp. isolated from water caused the precipitation of iron from a suspension of colloidal ferric iron at pH 6.0 and 7.6. Iron-encrusted cells of the bacterium formed large aggregates. The amount of iron removed from the colloidal preparation in the form of aggregates was from 21 to 52% at pH 7.6 and 49% at pH 6.0 by the bacterial cells. Endogenous respiration rates of the iron-encrusted cells were from 32 to 72% lower than the rates for unencrusted cells. Respiration rates, measured polarographically in the presence of glucose, were also greatly reduced by the coating of iron on the cells
