The SPMO has characterized the diversity of eubacteria, archaea, fungi, algae, and cyanobacteria from GSP soil and water. Our primary approach was to isolate hundreds of microbes into pure culture, characterize their physiology and biochemistry, and sequence their 16/18S rRNA genes. A subset of fifty unique strains of cyanobacteria and algae has been deposited in national culture collections, and efforts are underway to deposit selected heterotrophic bacteria. Many GSP microbes grow at salinities from nearly fresh water to at least half-saturation, and survive prolonged periods at levels approaching saturation. We have shown selected bacteria to have high rates of spontaneous mutation and constitutive DNA repair. We have isolated bacteriophages associated with GSP bacteria, suggesting a role for transduction in bacterial adaptation at the GSP. A culture-independent clone library of cyanobacterial diversity revealed adequate representation among isolates in some clades, but poorer coverage in others. All of these observations are consistent with the hypothesis that a dynamically stressful GSP environment drives microbial adaptive radiation below the genus level.
