Researchers studied bacteria in saline water wetlands in Golestan province. They collected 70 water samples and found 41 bacteria that can survive in salty environments. Most of these bacteria were found in wetlands and geysers. The bacteria from Alagol wetland had the highest abundance. Some of the bacteria had enzymes for breaking down starch, proteins, and fats. Most bacteria grew at similar rates, except for two species that were slower.
