The influence of Acidification on Ammonification
This experiment examines the influence of moderate (pH 5.5) to extreme (pH 3.5) sulfuric acid-induced acidification on the ability of soil microorganisms to conduct ammonification. Two common soil inhabiting bacteria, Pseudomonas aeruginosa and Bacillus cereus, are analyzed for their ability to perform ammonification given only organic nitrogen and their ammonification ability in an acidic environment. The effect of acidification on the amount of ammonification in a local soil sample is also examined.

| Pedagogical Use Description | Students will learn to complete a simple experiment involving the manipulation of one variable that influences the outcome of the physiological events of a population of organisms. They will also gain an understanding of the effect of pH on the efficiency of organic degradation by soil microbes. |
