This reference illustrates the applying of basic strategies in microbiology to supply a valid foundation for the layout and operation of varied organic platforms utilized in fixing quite a few environmental demanding situations within the air, water, and soil—opening with an exam of total metabolism and the ensuing progress of micro organism, fungi, algae, protozoa, rotifers, and different microorganisms and progressing to combined microbial platforms the place a variety of teams of microorganisms compete, in addition to, praise one another within the processing of a myriad of biodegradable pollution in the environment.

Example text

The initial energy step of nitrification is shown in Equation 2-3. 2 kJ/g N. A second group of aerobic bacteria can oxidize the nitrous acid to nitric acid, the most oxidized form of nitrogen, Equation 2-4. 1 kJ/g N. The second group of bacteria does not obtain as much energy as the first group of bacteria, but that does not diminish their importance. The bacteria that oxidize ammonia to nitric acid are known as nitrifying bacteria. The group of nitrifying bacteria that oxidize ammonia to nitrous acid are designated as the Nitroso- bacteria; and the group of nitrifying bacteria that oxidize the nitrous acid to nitric acid are designated as the Nitro- bacteria.

Alanine has the chemical formula, C3H7O2N; while propionic acid has the chemical formula, C3HfO2. 2 kJ/g. 6 kJ/g. The difference between the heats of combustion of the two acids lies in the amino nitrogen group that is oxidized to nitrogen gas in the combustion reaction. While amino acids yield more total heat energy than their corresponding fatty acids, the energy yield/g is less. The energy yield for bacteria metabolism is even less than the chemical oxidation reaction, since their oxidation reaction yields carbon dioxide, water, and ammonia instead of carbon dioxide, water, and nitrogen gas.

The protein part of the enzyme has been designated as the apo-enzyme. The reactive part of the enzyme is a highly specialized chemical structure that can be used over and over again in different proteins to bring about the same chemical reaction with different chemical compounds. This reactive part of the enzyme is called the co-enzyme. The co-enzyme is assisted by a series of metallic activators. The metabolic activators tend to be the reactive points of the co-enzymes. There are a number of heavy metals that act as metallic activators, ton (Fe) is the most common metallic activator in bacteria enzymes.
