Predatory bacterium

Patent Granted Some species of bacteria kill and then consume other microorganisms, these species called predatory bacteria.[150] These include organisms such as Myxococcus xanthus, which forms swarms of cells that kill and digest any bacteria they encounter.[151] Other bacterial predators either attach to their prey in order to digest them and absorb nutrients, such as Vampirococcus, or invade another cell and multiply inside the cytosol, such as Daptobacter.[152] These predatory bacteria are thought to have evolved from saprophages that consumed dead microorganisms, through adaptations that allowed them to entrap and kill other organisms.
