Question

What do you mean by fermentors?

Answer 1

Hint: The fermentor is a large apparatus which is used for the fermentation activity of the microorganisms for the commercial production on a large scale of a certain substance.

Complete step-by-step answer:
A fermentor is a culture system to produce organisms or cells. It is designed to give the right environment for optimal growth and metabolic activity of the organisms.
A fermentor can be made up of glass vessels with a flat and round bottom. The top flanged carrying plate. This can be sterilised by using autoclaving. Another type of fermentor is a glass cylinder with bottom plates and stainless steel top.
Components of fermentor
Body: The body of the fermentor can be made up of glass or stainless steel. The fermentor used in industrial-scale is generally preferred to use stainless steel, nickel, chromium, etc fermentor. The fermentor made up of glass is very good because it provides a smooth surface, corrosive proof, non-toxic, and easy to observe the interior of the vessels.
Seal: This separates the body from the top plate and prevents air leakage.
Impeller/Agitator: It maintains a uniform condition throughout the vessel.
 Baffles: It is the metal strip attached radially to the side of the fermentor wall. It will improve the aeration efficiency.
Spargers: It is connecting to the air supply and responsible for aeration. It creates the air bubbles to medium.
Fermentors can improve the quality of the product, save time and fewer labours and also produce the microorganisms on a huge large scale.

Note: There are many applications of fermentor such as used in biopharmaceuticals, in food industries, chemical production and other production. It also helps with research and development.
