Truepera

• 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 sugars, organic acids and amino acids.
• Species: Truepera radiovictrix.
