Thermotoga maritima

Thermotoga maritima is a non-spore forming, rod-shaped bacterium which was originally isolated from geothermal-heated marine sediment. Its optimal growth temperature is approximately 80C (176F). Thermotoga is phylogenetically very important, because it appears to be one of the deepest lineages in Eubacteria. The genome of Thermotoga is a single circular chromosome of approximately 1.8 Megabases in size, encoding for an estimated 1877 proteins. Since the Thermotoga genome has the highest percentage (24%) of genes similar to Archeal genes, Thermotoga may prove to be an ideal system to study domain organization and identify new protein folds in both Eubacteria and Archea.
