Iron-oxidizing bacteria (or iron bacteria) are chemotrophic bacteria that derive energy by oxidizing dissolved iron. They are known to grow and proliferate in waters containing iron concentrations as low as 0.1 mg/L. However, at least 0.3 ppm of dissolved oxygen is …

2016年4月13日 · Microorganisms, known as “iron bacteria” or “iron-eating bacteria,” are commonly found in soil, surface water and shallow groundwater. While most bacteria get their energy from decomposing organic matter, these bacteria …

2021年11月19日 · The bacteria essentially “eat” ferrous iron, which is common and able to react with other elements in oxygen-free (anaerobic) environments. Wetlands are classic examples of anaerobic soils, and the mucky conditions of a stream floodplain are ideal for iron bacteria.

2020年7月16日 · Scientists have discovered a type of bacteria that eats and gets its calories from metal, after suspecting they exist for more than a hundred years but never proving it.

2024年10月18日 · Iron bacteria are small living organisms that naturally occur in soil, shallow groundwater, and surface waters. These bacteria combine iron (or manganese) and oxygen to form deposits of "rust," bacterial cells, and a slimy material that sticks the bacteria to well pipes, pumps, and plumbing fixtures.

2024年7月30日 · When de-oxygenated groundwater reaches an oxygen source, iron bacteria use the oxygen to convert the ferrous iron into ferric iron, changing the iron into a slimy rust-colored residue made up of living and dead bacteria, secretions, sheathes, stalks, and other materials the bacteria left behind.

2024年9月16日 · Iron bacteria use dissolved iron or manganese in groundwater to grow, producing a bacterial slime along the way. While these bacteria can be off-putting, they are typically considered more of a nuisance than a health hazard.

At least 18 types of bacteria are classified as iron bacteria, long thread-like bacteria that “feed” on iron and secrete slime. Unlike most bacteria, which feed on organic matter, iron bacteria fulfill their energy requirements by oxidizing ferrous iron into ferric iron.

The 'iron-eating bacteria', fact or fable? A year ago, iron-eating bacteria were all over the news because ships in the port of Ghent Terneuzen suffered from very rapid corrosion damage. The suspected cause was microbiological, otherwise known as MIC corrosion.

2021年11月2日 · The bacteria essentially “eat” ferrous iron, which is common and able to react with other elements in oxygen-free (anaerobic) environments. Wetlands are classic examples of anaerobic soils, and the mucky conditions of a stream floodplain are ideal for iron bacteria.
