Species

Natranaerobius thermophilus

Description and Significance

N. thermophilus is a rod-shaped, non-motile, non-sporeforming bacteria. It is also an obligate anerobe and Gram-positive. Being a polyextremophile, it thrives in multiple extremes of the environment. N. thermphilus optimally grows at 53°C, with a culturable temperature range of 30-57°C. The bacteria are also obligate alkaphiles and obligate halophiles. N. thermophilus grows at an optimum pH of 9.5 (range of pH 8.5-10.6) at 55°C. The bacteria also grow at an optimal salt concentration of 3.3-3.9 M Na+ (range 1.5-4.9 M Na+).
