Complete Question (in order)
The growth of baker's yeast (S. cerevisiae) on glucose may be simply described by following equation:
C₆H₁₂0₆ + 30₂ + 0.48 NH₃ => 0.48C₆H₁₂NO₃ + 4.32H₂O + 3.12CO₂ yeast
In a batch reactor of volume 10 1, the final desired yeast concentration is 50 gdw/1.
a. Determine the concentration and total amount of glucose and (NH4)₂SO4 in the nutrient medium.
b. Determine the yield coefficients [tex]Y_{x/s}[/tex] (biomass/glucose) and [tex]Y_{x/o}[/tex] (biomass/oxygen).
c. Determine the total amount of oxygen required.
d. If the rate of growth at exponential phase is [tex]r_x[/tex] = 0.7 gdw/l-h, determine the rate of oxygen consumption (g O₂/1-h)
e. Calculate the heat-removal requirements for the reactor (recall equation 6.26).
Answer:
a. 2.3 × 10⁴ kg
b. 0.384 and 0.72
c. 6.94 × 10³ kg
d. 0.973
Explanation:
The given equation that describes the growth of baker's yeast on glucose
C₆H₁₂0₆ + 30₂ + 0.48 NH₃ => 0.48C₆H₁₂NO₃ + 4.32H₂O + 3.12CO₂ yeast
The volume of batch reactor is given as 10⁵ Liters
The final desired yeast concentration is 50 gdw/l
