Gallionella cells are kidney-shaped or spherical and located at the end of a long "stalk". Among them, the long axis of the cell is perpendicular to the axis of the stalk. A stalk is a bundle of fibers intertwined with each other, and the filaments can branch. They can be covered with ferric hydroxide without precipitating manganese compounds. Gallionella reproduces by cell division, initially with daughter cells still at the end of the stalk, and later they can be released as motile cells. Motile cells move with 1 to 2 polar or subpolar flagella.

Gram staining of Gallionella was negative. Since they assimilate considerable amounts of C14O2 while oxidizing ferrous iron to high iron, Gram staining of Gallionella was negative. Since they assimilate considerable amounts of C14O2 while oxidizing ferrous iron to high iron, they may be mineralized energy nutrients. Gallionella grow in inorganic synthetic medium and natural low-nutrient water. Ferric hydroxide can make up 90% of the dry weight of the cell population. Gallionella is a microaerophilic bacterium that develops at an oxygen concentration of approximately 1 mg/L. Its optimum growth pH is 6-7. Gallionella is found in water and soil that are low in iron. It is often associated with Leptothrix ochracea and is associated with the precipitation of large amounts of iron oxide. The growth of these bacteria can cause water quality problems.
Creative Biogene offers customizable Gallionella strain culture services. This service can help you obtain Gallionella cultures for subsequent scientific research. This service allows you to skip the complicated and tedious groping of culture conditions, which helps to speed up research on this strain.
Gallionella ferruginea has the same morphology as its genus. The shank is a bifurcated, flat wound band, 0.4-1.0 microns wide, formed from a large number (up to 90) of filaments. Under suboptimal conditions there were more bifurcations and apparently less entanglement.
Gallionella filament has the same morphology as its genus. The shank is usually composed of less than 12 filaments with helically wound hairpins. It was originally isolated from the drainage water of the Jachroma swamp near Moscow, Soviet Union. Less common in iron-containing water.
