Question

What is a bioreactor used for? Name a commonly used bioreactor and any two of its components.

Answer 1

Hint: A bioreactor is a computed device or system that supports a biologically active environment. These are commonly cylindrical, ranging in size from liters to cubic meters.

Complete Answer:
- A bioreactor is a vessel during which a chemical change is administered which involves organisms or biochemically active substances derived from such organisms. Bioreactors contain a buried trench with wood chips through which the tile water flows before entering a surface water body. Microorganisms from the soil colonize the wood chips.
- These microorganisms "eat" the carbon from the wood chips and "breathe" the nitrate from the water. The installation cost of a bioreactor is around $8000 which usually includes control structures, wood chips and excavation costs.
- The first purpose of a wood chip bioreactor is to get rid of nitrates from subsurface tile drainage water at the sting of a field before the water enters a ditch or a stream. Bioreactors don't interrupt any practices occurring within the field, nor do they modify the effectiveness of tile drainage systems. A wood chip bioreactor is taken into account an edge-of-field practice.

Some of the commonly used bioreactors are Simple stirred tank bioreactor, Sparged stirred - tank bioreactor.
- A Simple stirred tank bioreactor composed of a reactor and a mixer like a stirrer, a turbine wing, or a propeller. It's useful for substrate solutions of high viscosity and for immobilized enzymes with relatively low activity.
- Stirred tank bioreactors are the reactors most generally employed for culturing biological agents like cells, enzymes, or antibodies. they're contractors where the well-mixed among phases is obtained mainly by internal mechanical agitation. it's an agitator, an oxygen delivery system, a foam controller, a temperature controller, pH, controller, and sampling ports in order that cultures are often withdrawn periodically.

Note: Bioreactor and fermentor are two words for the same thing. Scientists who cultivate bacteria, yeast, or fungi often use the term fermentor. The term bioreactor often relates to the cultivation of mammalian cells but is also generically used.
