1. Publisher's Website

The most straightforward place to start is the publisher's website. Bioprocess Engineering: Basic Concepts is a well-known textbook in the field, and its publisher might offer supplementary materials, including solution manuals, for instructors or sometimes for students who have verified their course enrollment. Search : Look up the textbook on the publisher's website (e

Problem 4: Oxygen Transfer Rate (OTR)

Concept: Aeration is critical in aerobic fermentation. The OTR depends on the mass transfer coefficient ($k_L a$) and the driving force (difference between saturation and actual oxygen concentration).

Problem Statement: A fermenter has a volumetric mass transfer coefficient ($k_L a$) of $100\text h^-1$. The saturated dissolved oxygen concentration ($C^*$) is $7\text mg/L$. The critical dissolved oxygen concentration for the cells to remain aerobic is $1\text mg/L$. What is the maximum Oxygen Uptake Rate (OUR) the system can support without the dissolved oxygen falling below the critical level?

Solution:

  1. Understand the relationship: For steady-state operation, OTR (supply) must equal OUR (demand). $$ \textOTR = k_L a (C^* - C_L) $$ To find the maximum OUR supported, we assume $C_L$ stays at the critical limit ($1\text mg/L$).

  2. Calculate the concentration driving force: $$ C^* - C_L = 7\text mg/L - 1\text mg/L = 6\text mg/L $$

  3. Calculate OTR: Note: Convert $k_L a$ to seconds or keep in hours. Let's use hours. $$ \textOTR = 100\text h^-1 \times 6\text mg/L $$ $$ \textOTR = 600\text mg O_2/\textL\cdot\texth $$ Problem 4: Oxygen Transfer Rate (OTR) Concept: Aeration

    Convert to more standard units (g/L/h): $$ \textOTR = \mathbf0.6\text g/L/h $$

3. Representative solved-problem types (with brief solution approaches)

  1. Estimating growth rate from batch data
    • Fit ln(X) vs. time in exponential phase to get μ; use Monod to relate μ to substrate concentration.
  2. Material balance for fed-batch reactor with substrate feed
    • Write dX/dt, dS/dt including feed terms; solve analytically for simple cases or integrate numerically.
  3. Designing a CSTR for target conversion
    • Use steady-state mass balances: F0C0 − FC − rV = 0; solve for V given r (which may depend on C).
  4. Calculating oxygen transfer requirement
    • Compute OUR from biomass and specific oxygen uptake; use kLa and (C* − CL) relation to size aeration/agitation.
  5. Heat removal sizing
    • Compute metabolic heat generation (qH per biomass), set Qremoved = UAΔT or use coolant correlation to size jacket area.
  6. Sterilization time (F0) calculation
    • Use first-order kinetics for microbial inactivation; integrate to get required time at given temperature for target log reduction.
  7. Scale-up using constant power/volume
    • Maintain P/V between scales; adjust impeller speed and size using dimensional relationships.
