Environmental Studies

By Ross E. McKinney

Compiling wisdom received via greater than 50 years of expertise in environmental engineering expertise, this ebook illustrates the appliance of basic ideas in microbiology to supply a valid foundation for the layout and operation of varied organic platforms utilized in fixing environmental demanding situations within the air, water, and soil. Environmental toxins keep an eye on Microbiology emphasizes the quantitative relationships of microbial progress and metabolism, starting an exam of the general metabolism and ensuing development of micro organism, fungi, algae, protozoa, rotifers, and different microorganisms and explains how micro organism lead to the stabilization of biodegradable natural toxins.

Example text

Most amino acids are created from short chain fatty acids. Alanine is a common amino acid that has a chemical structure similar to propionic acid. 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.

0 the ammonia nitrogen will exist as ammonium bicarbonate, ammonium chloride, ammonium sulfate or ammonium phosphate. The production of nitrous acid will create problems for the nitrifying bacteria unless there is adequate alkalinity to neutralize the nitrous acid as fast as it is formed. Sodium or calcium bicarbonates are the major forms of alkalinity in the natural environment to neutralize the nitrous acid. If ammonium bicarbonate is the form of ammonia being oxidized, its alkalinity will be destroyed as well as the sodium or calcium bicarbonate alkalinity required to neutralize the nitrous acid.

Stains add color to the bacteria, allowing them to be easily seen using the optical microscope. The staining procedure starts with a clean glass slide. A single drop of culture is placed on the glass slide and spread over the desired area of the slide with a sterile wire loop. The culture is allowed to dry in the air. It is then passed over a Bunsen burner flame to fix the bacteria lightly to the glass slide. A drop of the desired stain is placed over the dried smear and spread over the surface of the smear.
