Web1 sep. 2000 · The mechanism of oxidation of sulfur or hydrogen sulfide to sulfite is not known. However, various enzymes have been characterized from phototrophic or lithotrophic bacteria that are able to oxidize, for example, hydrogen sulfide to sulfur or thiosulfate to tetrathionate or to hydrolyze polythionates (16, 22). WebExamples include landfills and the digestive systems of cattle and humans. Lithotrophy corresponds to energy derived from compounds not containing any carbon, whereas organotrophy derives energy from the breakdown of compounds with at least one carbon-carbon bond. Forms of Phototrophy . 1. Bacteriorhodopsin – ancient form of phototrophy
These organisms are photosynthetic; examples of photolithotrophic bacteria are purple bacteria (e. g., Chromatiaceae ), green bacteria ( Chlorobiaceae and Chloroflexota ), and "Cyanobacteria". Purple and green bacteria oxidize sulfide, sulfur, sulfite, iron or hydrogen.

WebIn technology, this is referred to as microbially influenced corrosion (MIC). Contrary to the more prominent rusting of iron with oxygen, MIC usually is a hidden process occurring in places such as closed cooling water systems or buried pipelines.

Web9 okt. 2024 · For example, when blue light is abundant, it mainly produces carotenoids (taking on a rusty orange color). During phytoplankton blooms or while growing under dense plant/macroalgae canopies, blue light can become scarce. Under these conditions, it mainly produces bacteriochlorophylls (taking on a purplish color) to scavenge red light.
