Truepera

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 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.[1][2]
