Abstract
An improved inorganic medium for the obligate chemoautotrophic iron bacterium Ferrobacillus ferrooxidans that will support the growth of 2-4 x 108 cells/ml is described, to- gether with a method of harvesting cells relatively free from the ac-companying precipitate of oxidized iron. The demonstration of the co-incidence of ferrous iron oxidation and growth further confirms the autotrophy of this organism. Some observations concerning the nutri-tion and morphology of F. ferrooxidans are presented. The suitability of this organism for studies of Fe metabolism is emphasized.Keywords
