Description and Significance
S. americana is an extremophile. It has been found in the highly alkaline anaerobic environment of Mono Lake, California. S. Americana can also inhabit areas with high sulfur and salt concentrations. S. americana has scientists especially excited. Some believe that the harsh environment of Mono Lake is similar to that of Mars, giving hope to the theory that life existed there. [1, 2] S. americana is an obligate anaerobe and has an optimal pH range of 8.0 - 10.5. [2]Cells of the Gram-negative strain were motile and spirochaete-shaped with sizes of 0.2-0.22 x 8-18 microm.[3]
