Question

Read the following statements w.r.t. bioreactors:

a. In large bioreactors, 100-1000 litres of volume of cultures can be processed.
b. Optimum conditions are provided for achieving desired products.
c. The most commonly used bioreactors are of stirring type.

Choose the option with:
a. All true statements.
b. All false statements.
c. Some true and some false statements.
d. Only one true statement.

Answer 1

After evaluating each statement about bioreactors, all statements are accurate. Bioreactors can process large volumes, maintain optimum conditions for product yield, and stirring types are widely used in industry.

Step-by-step explanation:

The question pertains to the characteristics and functioning of bioreactors used in fermentation technology. By analyzing each statement provided, we can determine their accuracy:

• Large bioreactors can indeed process 100-1000 litres of culture volume, which is needed for the commercial-scale production of various products.
• Within these bioreactors, optimum conditions such as temperature, pH, and oxygen availability (for aerobic organisms) or the exclusion of oxygen (for anaerobic organisms) are meticulously maintained to maximize the yield of desired products.
• Stirring-type bioreactors are commonplace in the industry as they allow for efficient mixing and aeration, which are crucial for the growth and productivity of the microbial cultures or cell lines.

Considering the practical uses and characteristics of bioreactors such as feb-batch fermentation, continuous fermentation, and the nature of aerobic and anaerobic conditions provided for microbial growth, all statements provided in the question are factual and reflect common practices in fermentation technology.

Therefore, the correct option in relation to the statements given is:

(a) All true statements.
