Study Notes
Overview of Bioreactors
- Bioreactors facilitate biochemical reactions by providing an optimal environment for whole cells or enzymes to convert substrates into desired products.
- They are also utilized in applications like water treatment to inactivate or sterilize cells.
Types of Bioreactors
- Stirred Tank Bioreactor: Commonly used for cell growth and enzyme production.
- Packed Bed Bioreactor: Suitable for processes involving immobilized cells.
- Fluidized Bed Bioreactor: Offers enhanced mass transfer rates and is used for heterogeneous reactions.
- Airlift Bioreactor: Promotes mixing through air bubbles, suitable for delicate cell cultures.
- Bubble Column Bioreactor: Utilizes gas bubbles to promote mixing, often used in fermentation processes.
Applications of Bioreactors
- Bioreactors are versatile, used in various fields including:
- Cell growth and maintenance
- Enzyme production and catalysis
- Food and beverage production, including milk processing
- Tissue engineering and regenerative medicine
- Protein synthesis and algae production
- Anaerobic digestion processes and chitinolytic cultures
Key Parameters for Bioreactor Efficiency
- Specific operational parameters are crucial for optimal bioreactor function:
- Temperature: Must be maintained within a range suitable for the target organism.
- Mixing Rate: Proper agitation ensures uniform nutrient distribution and prevents sedimentation.
- Nutrient Transfer: Adequate supply of nutrients is necessary for cell growth and activity.
- Gassing: Appropriate levels of oxygen or other gases must be provided, especially for aerobic processes.
Parts of a Bioreactor
- Various components work synchronously to create conducive conditions:
- Temperature Control: Regulates heater/cooler mechanisms.
- Nutrient Feed System: Supplies essential nutrients to the bioreactor.
- Aeration Device: Introduces gas into the culture medium.
- pH Control System: Maintains optimal acidity or alkalinity levels for biological processes.
