Document Summary
Bacteria exhibit incredible diversity in their metabolic processes! Just about every substance known, whether natural or synthetic, can be metabolized by some bacterium or another. That"s why bacteria can be used to clean up toxic waste dumps and oil spills in the process known as bioremediation. Metabolic processes can be very useful in identification of specific bacteria. In lab 8, we looked at various aspects of metabolism using known bacteria and your pets. You should know the purpose of each of these tests and what the plates or tubes look like. Here are some examples of the different metabolic tests you looked at: Starch plates allow us to detect production of extracellular amylase enzymes. After incubation the plates were flooded with iodine, which reacts with any starch remaining in the plate to give a blue- black color. Bacillus subtilis grows very well on the starch agar plate.
