Truepera is one genus of bacteria in the family from the phylum Deinococcus-Thermus. 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; 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 s
