Dimeroituneinella

Dimeroituneinella is a genus of bacteria from the family Rhodospirillaceae, which is part of the class Alphaproteobacteria. This genus was first described in 2013 and is characterized by its ability to perform anaerobic respiration, using nitrate as the terminal electron acceptor. Dimeroituneinella species are typically found in environments with low oxygen levels, such as sediments and water columns of marine and freshwater habitats.

The genus includes several species, with Dimeroituneinella halophila being one of the most well-studied. This species is known for its ability to grow in high-salt environments, making it an interesting subject for research into extremophilic bacteria. Dimeroituneinella species are also notable for their unique metabolic pathways, which include the use of dimethylsulfoniopropionate (DMSP) as a carbon and energy source.

Dimeroituneinella bacteria are typically motile, with a single polar flagellum, and are rod-shaped. They are Gram-negative and have a cell wall structure that is typical of alphaproteobacteria. The genus is named after the dimeric form of the cytochrome c3 protein, which is a key component of the respiratory chain in these bacteria.

Research on Dimeroituneinella is ongoing, with scientists studying their role in nutrient cycling, their potential for bioremediation, and their ecological significance in various environments. The genus represents an important group of bacteria that contribute to our understanding of microbial diversity and function in low-oxygen environments.
