Truepera is one genus of bacteria in the family Trueperaceae from the phylum Dienococcus-Thermus. Following points accounts for its characters:
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 kGyThese strains are chemo-organotrophic and aerobic; 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 acids.Species: Truepera radiovictrix.
