Biological oxidation of phenylacetic acid is inhibited by propionic acid present in wastewater. The following data were obtained for enzymatic oxidation of phenylacetic acid at different concentrations of propionic acid:S (mM) 0.25 0.40 0.50 0.60 0.75 1.00V (mM/l-h), I = 0 1.0 1.7 1.9 2.1 2.4 2.5V (mM/l-h), I = 1 mM 0.65 1.1 1.3 1.4 1.8 2.2V (mM/l-h), I = 2 mM 0.55 0.9 1.0 1.3 1.4 1.8(a) What kind of inhibition is this?(b) Determine Vm, Km, and KI.
