Bacillus subtilis growing on methanol has a maximum growth yield coefficient of YM x/s = 0.45 g X/g S. The heat of combustion of cells is 5.64 kcal/g cells and for combusting the substrate (AH) is 7.2 kcal/g-methanol. A. Determine the metabolic heat generated by the cells per unit mass of methanol consumption, YA/s (in kcal/g S). (Hint: see class notes} The cells are growing in the exponential growth phase in a 4.5 L chemostat reactor with a steady state cell concentration of [X] = 10.8 g/L and a feed concentration of 28.3 g/L methanol, at the maximum specific growth rate, μmax, of 0.87 h¨¹. B. At what rate must heat be removed from the reactor to maintain an isothermal reactor (in kcal/h)?

Question
![Bacillus subtilis growing on methanol has a maximum growth yield coefficient of YM x/s = 0.45 g X/g S. The heat of
combustion of cells is 5.64 kcal/g cells and for combusting the substrate (AH) is 7.2 kcal/g-methanol.
A. Determine the metabolic heat generated by the cells per unit mass of methanol consumption, YA/s (in kcal/g
S). (Hint: see class notes}
The cells are growing in the exponential growth phase in a 4.5 L chemostat reactor with a steady state cell
concentration of [X] = 10.8 g/L and a feed concentration of 28.3 g/L methanol, at the maximum specific growth
rate, μmax, of 0.87 h¨¹.
B. At what rate must heat be removed from the reactor to maintain an isothermal reactor (in kcal/h)?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6fb3429f-a406-4812-82fc-346d6a20f662%2F4ed8bf09-2fc8-418b-b989-517005fff30b%2F4y4iyt_processed.png&w=3840&q=75)
