The anoxygenic phototrophic iron oxidation was the first anaerobic metabolism to be described within the iron anaerobic oxidation metabolism. The photoferrotrophic bacteria use Fe 2+ as electron donor and the energy from light to assimilate CO 2 into biomass through the Calvin Benson-Bassam cycle (or rTCA cycle) in a neutrophilic environment (pH 5.5-7.2), producing Fe 3+ oxides as a waste ...
Bacteriological water analysis is a method of analysing water to estimate the numbers of bacteria present and, if needed, to find out what sort of bacteria they are. It represents one aspect of water quality. It is a microbiological analytical procedure which uses samples of water and from these samples determines the concentration of bacteria ...
Acidithiobacillus ferrooxidans is a bacterium that sustains its life cycle at extremely low pH values, and it is one of the very few organisms that gain energy from oxidating ferrous iron (Fe +II). It can make copper from ores water-soluble, and it can sequester both carbon and nitrogen from the atmosphere. [1]
The iron in the water is then oxidized by dissolved oxygen or, through enzyme catalysis by iron bacteria (e.g., Thiobacillus ferrooxidans and Thiobacillus thiooxidans) that concentrate the iron as part of their life processes. [4] Presence of these bacteria can be detected by the oily film they leave on the surface of the water. [3]
Acidithiobacillus is a genus of the Acidithiobacillia in the phylum "Pseudomonadota".This genus includes ten species of acidophilic microorganisms capable of sulfur and/or iron oxidation: Acidithiobacillus albertensis, Acidithiobacillus caldus, Acidithiobacillus cuprithermicus, Acidithiobacillus ferrianus, Acidithiobacillus ferridurans, Acidithiobacillus ferriphilus, Acidithiobacillus ...
R2A agar (Reasoner's 2A agar) is a culture medium [1] developed to study bacteria which normally inhabit potable water. [2] These bacteria tend to be slow-growing species and would quickly be suppressed by faster-growing species on a richer culture medium.
