Gallionella ferruginea is able to utilize Fe II and the reduced sulfur compounds sulfide and thiosulfate as electron donor and energy source. Tetrathionate and elemental sulfur, on the other hand, are not metabolized. In sulfide-O 2 microgradient cultures G.

The 16S rRNA gene of Gallionella ferruginea was amplified by polymerase chain reaction and sequenced by direct double-stranded sequencing. The phylogenetic analysis placed G. The published phenotypic characteristics of G. It grows auto- and mixotrophically with CO2, glucose, fructose and sucrose as carbon sources, ferrous iron as an electron donor and ammonium or nitrate as nitrogen sources. Two G. An iron-oxidizing bacterium without stalk-forming ability, but with the same growth pattern as G. This indicates that the stalk is not essential for growth.

A Microbial Biorealm page on the genus Gallionella. Gallionella ferruginea is an iron-oxidizing chemolithotrophic bacterium that has been found in a variety of different aquatic habitats. It has been known for years that these bacteria play an important part in oxidizing and fixing iron. Gallionella ferruginea is an iron-oxidizing, chemolithotrophic bacteria that lives in low-oxygen conditions. The bacteria oxidize and fix iron, but in order to get energy out of this process, they must live in a relatively specific environment that contains "reduced iron, the right amount of oxygen and sufficient amounts of carbon, phosphorus and nitrogen" Halbach, Koschinsky, and Halbach
