A bioreactor is a system for cultivating living cells and microorganisms under controlled conditions to produce desired products. Various types include stirred tank, air-lift, packed bed, membrane, fluidized bed, and photobioreactors, each designed for specific applications like fermentation and enzyme production. Key features of these bioreactors involve mixing, gas sparging, and light usage for optimal growth and product efficiency.

2. WHAT IS BIOREACTOR
A bioreactor is a device or system that
provides a controlled environment for the
cultivation of living cells, microorganisms, or
biological processes. It facilitates the growth,
metabolism, and production of desired
products by maintaining optimal conditions
such as temperature, pH, nutrient supply, and
oxygen levels.
