Abstract

Close
- Three recently isolated extremely acidophilic archaeal strains have been shown to be phylogenetically similar to Ferroplasma acidiphilum Y(T) by 16S rRNA gene sequencing. All four Ferroplasma isolates were capable of growing chemoorganotrophically on yeast extract or a range of sugars and chemomixotrophically on ferrous iron and yeast extract or sugars, and isolate "Ferroplasma acidarmanus" Fer1(T) required much higher levels of organic carbon. All four isolates were facultative anaerobes, coupling chemoorganotrophic growth on yeast extract to the reduction of ferric iron. The temperature optima for the four isolates were between 35 and 42 degrees C and the pH optima were 1.0 to 1.7, and "F. acidarmanus" Fer1(T) was capable of growing at pH 0. The optimum yeast extract concentration for "F. acidarmanus" Fer1(T) was higher than that for the other three isolates. Phenotypic results suggested that isolate "F. acidarmanus" Fer1(T) is of a different species than the other three strains, and 16S rRNA sequence data, DNA-DNA similarity values, and two-dimensional polyacrylamide gel electrophoresis protein profiles clearly showed that strains DR1, MT17, and Y(T) group as a single species. "F. acidarmanus" Fer1(T) groups separately, and we propose the new species "F. acidarmanus" Fer1(T) sp. nov.
