Deinococcota ''Deinococcota'' (synonym, ''Deinococcus-Thermus'') is a phylum of bacteria with a single class, ''Deinococci'', that are highly resistant to environmental hazards, also known as extremophiles. These bacteria have thick cell walls that give them ...

''. The following points accounts for its characteristics: * These strains form orange/red colonies and have spherical-shaped cells. * Optimum growth temperature of about 50 °C. * Optimum pH for growth between about 7.5 and 9.5, and do not grow at pH below 6.5 or above pH 11.2. * They are extremely resistant to ionizing radiation. For instance up to 60% of the cells can survive even after being exposed to 5.0 kGy * These strains are chemo-organotrophic and

aerobic Aerobic means "requiring air," in which "air" usually means oxygen. Aerobic may also refer to * Aerobic exercise, prolonged exercise of moderate intensity * Aerobics, a form of aerobic exercise * Aerobic respiration, the aerobic process of cel ...

; do not grow in ''Thermus'' medium under anaerobic conditions with or without nitrate as electron acceptor and glucose as a source of carbon and energy, but ferment glucose to d-lactate without formation of gas. They assimilate a large variety of sugars, organic acids and

amino acid Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids, which comprise proteins. Only 22 alpha a ...

s. * Species: ''Truepera radiovictrix.'' The sole species of this genus, ''Truepera radiovictrix,'' can be distinguished from other Deinococci as well as all other bacteria by the presence of five

conserved signature indels Conserved signature inserts and deletions (CSIs) in protein sequences provide an important category of molecular markers for understanding phylogenetic relationships. CSIs, brought about by rare genetic changes, provide useful phylogenetic markers ...

(CSIs) exclusively found in this species in the proteins such as chorismate synthase and CTP synthetase.
