Bacteria Discover the Advantages of Community


Fun Fact: Some species of bacteria are social creatures. They act as a community in a number of ways and because of this community behavior, their lives and their chance of survivability in adverse conditions is improved. Myxococcus xanthus is one such bacteria. They, like us, require a population that works together to enhance survivability. Like us communities of M. xanthus act as a singular unit, especially when they sense adversity. For instance; they move together to find food. If food is scarce, they reorganize themselves to become a complex organism with specialized, differentiated organ structures that is much more adaptable. Like us, this division of labor and specialization in their collective body structure enhances survivability. Along with increased mobility, some of the bacteria specialize in making spores to ensure survival through extreme conditions. They also specialize their behaviors to survive environmental changes like temperature and radiation. When damage occurs to their outer membrane M. xanthus cells cooperate with each other to make repairs in a process called Outer Membrane Exchange (OME). These bacteria have discovered the power of community – that looking out for each other is a much better strategy than competing with each other. When it comes to survival. This community trait in bacteria is also a clue to understanding the evolutionary transition to multi-cellularity.
