All organisms have specific environmental conditions in which they thrive. Most organisms cannot live in extremely salty environments. If a bacterium that normally lives in a fresh water environment is placed in an environment that is excessively salty, what will happen?

There are two groups of bacteria which live in the Great Salt Lake: Halobacterium and Halococcus. The Great Salt Lake's average salinity is around 13%. What class of microbes do the Halobacterium and Halococcus species belong to?
