EXPLANATION
Solid State (SSF) vs Submerged Fermentation (SmF): Aeration, Energy Consumption & Downstream
- Features of Solid-State Fermentation (SSF):
- Process Characteristics:
- Compact Bioreactor Volume: Due to minimal free liquid water, SSF utilizes smaller-volume bed/tray bioreactors with high product concentration per unit volume.
- Contamination Risks: Solid matrices can experience uneven heating, poor moisture diffusion, and difficulty in maintaining absolute aseptic barriers compared to fully sealed submerged fermenters.
- Official Answer Key: Designated (B) and (C) only as the correct choice.
- Conclusion: (B) and (C) only (Option 4).
Correct option: (4) (B) and (C) only.
