The key points from this module are as follows:

Bioreactors can be defined as a controllable environment enabling the biochemical and biomechanical elements to create a desirable biological product.

Consumer products made by biotechnology which include:

• Bread
• Vitamin B2,
• Personal care
• Cosmetics
• Food service ware
• Beverage packaging
• Plastic containers.

Significant points to be considered when designing bioreactors include:

• Capital investment and operating cost
• Prevent contamination,
• control and positively influence the biological reaction,
• Maintenance of adequate mass and heat transfer.

The most common features of a typical bioreactor are:

• Agitator system: it maintains a uniform environment through the vessel.
• Temperature and PH control system: Activation of acid or alkali pump to reduce the error.
• Sampling ports
• Cleaning and sterilization system
• Charging and emptying lines
• Foam-Control system

Some components of a typical bioreactor include the following:

• Agitator: it maintains a uniform environment through the vessel.
• Baffle: prevents vortex formation.
• Sparger: Introduces air into fermenter broth.
