Zusammenfassung

It is unknown to which extent phototrophic Fe(II) oxidation takes place in the simultaneous presence of organic electron donors (e.g., acetate/lactate). Therefore, the photoferrotrophic strain Rhodopseudomonas palustris TIE-1 was inoculated with various combinations of Fe(II), acetate and lactate to understand metabolic substrate preference. When acetate was provided together with Fe(II), TIE-1 consumed acetate first before Fe(II). When provided lactate plus Fe(II), TIE-1 consumed both substrates in parallel. When all three substrates were provided in one culture, TIE-1 used all substrates simultaneously. Our study suggests that the availability of alternative electron donors in addition to ferrous iron limits phototrophic iron oxidation.
