2. (20 pts) Cometabolism of trichloroethylene (TCE) by methylotrophic bacteria is considered an effective means of bioremediating a polluted aquifer. The bioremediation process includes oxidation of methane (MW 16) and co- metabolism of TCE (MW 131.5) as seenin reactions (1) and (2) below, respectively: (1) CH4 + 202 +4NAD 2C02 +4NADH2 (catabolism of methane by methylotrophic bacteria) (2) C2C13H+ 4NADH2 +3.502 2002 + 3H20 + 4NAD + 3HCI (co-metabolism of trichloroethylene by methylotrophic bacteria) Calculate the ratio (in mg 02/mg TCE) of consumed oxygen and degraded TCE during TCE co-metabolism
