					Beneficial Uses of Bacteria
             Fuel Production

•   Archaebacteria produce methane gas,
    which makes up 20% of the world’s
    natural gas used for fuel.
             Food Production

•   Lactobacillus and other
    bacteria turn milk into
    buttermilk, sour cream,
    yogurt, and cheeses.
•   Other bacteria turn apple
    cider into vinegar, and
    cucumbers into pickles.
       Environmental Clean-up

•   Some bacteria eat oil and turn it into
    environmentally friendly chemicals. These
    bacteria are dumped into waters
    contaminated by oil spills.
        Environmental Recycling

•   Bacteria are decomposers:
    they break down dead
    organisms into smaller
    chemicals which then go
    back into the soil.
                 Digestion

•   Many bacteria, such as human E. coli, live
    a warm and cozy life in your intestines.
    They help digest your food and make
    vitamins, such as Vitamin K (which is
    necessary for blood clotting).
             Digestive Health

•   Beneficial bacteria, such as Lactobacillus,
    keep the “bad” bacteria in check, by
    competing with them for nutrients.
              Medicines

•   The pharmaceutical industry uses some
    forms of bacteria to make vitamins and
    antibiotics.

•   Other bacteria can be used to produce
    insulin, which can be collected and given
    to people with diabetes.
                Food Chain

•   Bacteria are a food source for many small
    organisms!
