The biochemical characterization showed the positive interpretation for indole and catalase tests while methyl red, citrate, Voges-Proskaeur, urease production, nitrate reduction, tyrosine utilization, acetoin production and oxidase tests showed negative. Retrieved from ” https: Colony morphology of the bacterium Gallionella ferruginea while growing on the iron agar media. Reduced iron Right amount of oxygen and carbon Phosphorus and nitrogen It oxidizes dissolved iron, therefore removing it from the water and producing an insoluble precipitate of ferric hydroxide.

Gallionella – basic data. Gallionella ferrugineaand-iron bacterium – photo. Gallionella is an iron-oxidizing, chemolithotrophic bacteria that lives in low-oxygen conditions. Other iron hydroxide precipitates, such as jasper, can also be found in submarine hydrothermal fields that have relic filamental structures that indicate bacterial origin.

The bacterium is a kidney-shaped mycoplasmodial cell body that lacks peptidoglycan in its cell wall, which normally gives the wall its particular rigidity. The colonial growth was powdery, opaque and flat in elevation.


In active, deep sea hydrothermal venting sites, most of the iron mineralizations that come from the emitted hydrothermal fluids are massive sulphides.

Gallionella ferruginea is an iron-oxidizing chemolithotrophic bacterium that has been found in a variety of different aquatic habitats. A Simplified Guide to Bacteria in Water.

Could bacteria have fereuginea the Precambrian banded iron formations? Stromatolites – The Oldest Fossils. Serious problems can occur when these bacteria build up in well systems.

The bacteria were capable of fermenting glucose with the production of acid in anaerobic condition, but not in aerobic condition thus confirmed as Gallionella ferruginea.

They do not cause health problems, but they can have the following unpleasant effects:. Definition – What does Gallionella ferruginea mean? Gallionella ferruginea has been found in many different types of habitats such as: Preservation potential of iron -xidizing bacteria at seafloor hydrothermal vents.

Personal tools Log in. Gallionella ferruginea is an iron-oxidizing, chemolithotrophic bacteria that lives in low-oxygen conditions. Gallionella ferruginea is also known as iron bacteria.

Journal is inviting manuscripts for its coming issue. From MicrobeWiki, the student-edited microbiology resource.

Gallionela sp.

Ferruyinea it is difficult to eradicate gallionella ferruginea once they have entered well systems, prevention is the best safeguard. In active, deep sea hydrothermal venting sites, most of the iron mineralization from the emitted hydrothermal fluids are massive sulphides.


Gallionella habitates freshwater ferruginous mineral springs, shallow brackish waters, marine hydrothermal shallow galionella environments, and active, deep sea hydrothermal venting sites as well as in soil environments assocated with iron.

Though Gallionella grew well at a broad range pH values between 6. Back to Bukovy potok homepage. The bacterium is a kidney-shaped mycoplasmodial cell body and is generally covered in bacteriogenic iron oxide precipitate, which gives it a reddish-brown color. Biomobilisation and bioimmobilisation of metals.

Identifying Limiting Conditions for Coatings Specification. The Diversity of Metabolism in Procaryotes. Addition of NaCl in the iron added liquid media can inhibit the growth and multiplication of Gallionella ferruginea.

SEM image of sever Gallionella ferruginea stalks making up a network within a biofilm. They are gram negative kidney-shaped mycoplasmodial bodies found in clusters. A selective enrichment method for Gallionella Ferruginea These bacteria play an important role in oxidizing and fixing iron.

Gallionella ferruginea oxidize and fix iron, but in order to get energy out of this process, they must live in a relatively specific environment that contains:.
