    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.
