Questions and Answers
What is industrial fermentation?
Industrial fermentation is the process of using microorganisms such as bacteria, yeast, or fungi to produce various products on a large scale, such as pharmaceuticals, food products, and chemicals.
List four control variables of a bioreactor.
Four control variables of a bioreactor include temperature, pH level, agitation speed, and dissolved oxygen concentration.
Give an example of a product in each of the categories and the microorganism that produces that product( i)microorganism enzymes and (ii) biotransformation products
i) Example of a product produced by microorganism enzymes: Cheese produced by the microorganism enzyme rennet from calf stomach. ii) Example of a biotransformation product: Conversion of steroid precursors into steroid hormones by the microorganism Rhizopus arrhizus.

Study Notes
Industrial Fermentation
- A metabolic process that uses microorganisms to convert substrates (such as sugars) into desired products, often involving anaerobic or aerobic conditions.
- Used in the production of food, beverages, pharmaceuticals, and biofuels.
Control Variables of a Bioreactor
- Temperature: Critical for maintaining optimal growth conditions for microorganisms.
- pH: Must be monitored and controlled to ensure proper enzyme activity and growth rates.
- Dissolved Oxygen: Important for aerobic fermentation, influences growth and product formation.
- Agitation Speed: Helps in mixing the culture, enhancing mass transfer, and maintaining uniform conditions.
Examples of Products and Microorganisms
-
Microorganism Enzymes:
- Example: Amylase
- Microorganism: Bacillus subtilis
-
Biotransformation Products:
- Example: Ethanol
- Microorganism: Saccharomyces cerevisiae
Features of Software for Monitoring and Control of Fermentation Process
- Real-time data acquisition: Provides instant feedback on fermentation parameters.
- Automated control systems: Adjusts variables like temperature and pH automatically based on set points.
- User-friendly interface: Simplifies data visualization and process management for operators.
- Alerts and notifications: Notifies users of any deviations or errors in the fermentation process.
