Initial degradation rates of Phe as a function of [Phe] o . Shown is R o normalized to maximum initial degradation rates (R max ) for each experiment set (hypothesized to vary due to subtle differences in pretreatment of pyrite). Pyrite loadings of 100 g/L were used in all experiments. R max for each experiment set: A is 10.3 μM/hr, B is 4.69 μM/hr, C is 16.3 μM/hr, D is 18.9 μM/hr. Results illustrate the lack of first-order dependence of degradation as a function on the disappearance of Phe.
