From this data estimate the 48 hr and 96 hr TL m . Concentration of waste % Mortality % Mortality % by volume 48 hrs 96 hrs 40 85 100 20 60 100 10 30 70 5 0 35 3 0 20 2. Methanol (CH 3 OH) can be used as a heterotrophic energy source for bacteria. Determine the maximum energy that can be derived from methanol if: a) oxygen is the terminal electron acceptor b) sulfate is the terminal electron acceptor 1/6 CH 3 OH +1/6 H 2 O = 1/6 CO 2 + H + + e - G = - 8.9 kcal 3. What is the electron acceptor in the following reaction: 2 3 2 2 2 5 CH O 4 NO 4 H 5 CO 2 N 7 H O - + + + + + 4. Match the respiration reactions shown on the left below with the organism types on the right by writing the most appropriate roman numeral to the left of the reaction. _____a)
