Description and Significance
Halothemothrix orenii, of the order Haloanaerobiales, was named in honor of Aharon Oren who made important contributions to the understanding of halophilic anaerobic bacteria. H. orenii is unique amongst extremophiles as they have adapted to more than one environmental stresses. A halophilic, thermophilic, anaerobic, and fermentative bacterium, these types of organisms show to be rare in nature even after intensive search (Patel et al). Habitats in which H. orenii could thrive though are the salt lakes of Australia, Africa and the Middle East and petroleum reservoirs. H. orenii can be useful sources of enzymes with biotechnological applications such as sugar processing and hydrolysis after chemical treatment which usually occurs at high temperatures and results in high concentrations of salt (Patel et al). Being halophilic it can provide insights into the adaptations of proteins and metabolic pathways to produce this phenotype. This bacterium is also of particular significance because of its ability to manufacture hydrogen and is used in bioremediation of oil fields (Patel et al).
