Deltaproteobacteria
Deltaproteobacteria is a class of Proteobacteria. They are a varied group of bacteria that include a variety of types that do not share many common characteristics apart from their phylogenetic relatedness. They include sulfate-reducing bacteria, many of which are anaerobes, as well as a number of important genera whose members are predatory on other bacteria, such as Bdellovibrio and Myxobacteria.
Classification[edit | edit source]
The Deltaproteobacteria comprise a branch of the Proteobacteria and consist of several orders, which are:
- Desulfobacterales
- Desulfovibrionales
- Desulfurellales
- Desulfuromonadales
- Myxococcales
- Bdellovibrionales
Characteristics[edit | edit source]
Deltaproteobacteria are characterized by their ability to reduce sulfate and other similar substances. They are typically found in environments with a lot of organic material, such as sediments or the intestinal tracts of animals. Some members of this class are predatory and can invade other bacteria.
Ecological Role[edit | edit source]
Deltaproteobacteria play a significant role in the sulfur cycle. They are responsible for the reduction of sulfate to sulfide, a process that is important in the decomposition of organic matter. They also contribute to the cycling of other elements, such as carbon and nitrogen.
Medical Importance[edit | edit source]
While most Deltaproteobacteria are not pathogenic, some can cause disease in humans and animals. For example, Desulfovibrio species have been associated with inflammatory bowel disease.
