What is a major challenge in solid state fermentation (SSF) due to aerobic conditions in the bioreactor?
What is a major challenge in solid state fermentation (SSF) due to aerobic conditions in the bioreactor?
- Difficulty in controlling the moisture level
- Undesirable increase in temperature (correct)
- Local insufficient oxygen supply
- High aeration rates
How is the cooling of the SSF process achieved in the absence of a free aqueous phase?
How is the cooling of the SSF process achieved in the absence of a free aqueous phase?
- Through substrate mixing
- Through bioreactor double walls
- Via high aeration rates for evaporation (correct)
- By replenishing the water lost by evaporation
