Bacterium alters its genome to adapt to new conditions

Researchers: Achromatium is special in many respects: It is 30,000 times larger than its “normal” counterparts that live in water and owing to its calcite deposits it is visible to the naked eye. It has several hundred chromosomes, which are most likely not identical. This makes Achromatium the only known bacterium with several different genomes.
