The Effect of Micrococcus luteus, Escherichia coli, Enterobacter clocae, and Temperature on the Oxidation Rate of Iron

The purpose of this experiment was to determine if different types of bacteria, Micrococcus luteus, Escherichia coli, and Enterobacter clocae, had an affect on the oxygen levels in water leading to rust.  Pieces of iron were placed in the three different bacteria solutions, along with a control group of just water, and were allowed to collect a significant amount of rust so it could be read.  After the selected amount of time, it was concluded that Micrococcus luteus had the greatest difference in mass.  However, due to the amount of time allotted and the size of the initial piece of iron, a definite conclusion could not be drawn due to insufficient data.
