Which of the following is not a type of bioreactor?

  1. Stirred tank reactor

  2. Airlift reactor

  3. Fluidized bed reactor

  4. Packed bed reactor


Correct Option: D
Explanation:

Packed bed reactors are not typically used for bioprocesses, as they are not well-suited for the growth of microorganisms.

What is the purpose of a sparger in a bioreactor?

  1. To introduce oxygen into the culture

  2. To remove carbon dioxide from the culture

  3. To control the pH of the culture

  4. To prevent foaming in the culture


Correct Option: A
Explanation:

Spargers are used to introduce oxygen into the culture, which is essential for the growth of aerobic microorganisms.

Which material is commonly used for the construction of bioreactors?

  1. Stainless steel

  2. Glass

  3. Plastic

  4. Ceramic


Correct Option: A
Explanation:

Stainless steel is commonly used for the construction of bioreactors due to its durability, corrosion resistance, and ease of cleaning.

What is the function of a condenser in a bioprocess?

  1. To cool the process fluid

  2. To remove impurities from the process fluid

  3. To increase the pressure of the process fluid

  4. To decrease the volume of the process fluid


Correct Option: A
Explanation:

Condensers are used to cool the process fluid, which is necessary to prevent the process from overheating.

Which of the following is not a type of filter used in bioprocessing?

  1. Depth filter

  2. Membrane filter

  3. Centrifugal filter

  4. Cross-flow filter


Correct Option: C
Explanation:

Centrifugal filters are not typically used in bioprocessing, as they are not well-suited for the filtration of large volumes of fluid.

What is the purpose of a chromatography column in a bioprocess?

  1. To separate different molecules in a mixture

  2. To purify a product

  3. To concentrate a product

  4. To remove impurities from a product


Correct Option: A
Explanation:

Chromatography columns are used to separate different molecules in a mixture based on their different properties.

Which of the following is not a type of chromatography used in bioprocessing?

  1. Size exclusion chromatography

  2. Ion exchange chromatography

  3. Affinity chromatography

  4. Gas chromatography


Correct Option: D
Explanation:

Gas chromatography is not typically used in bioprocessing, as it is not well-suited for the separation of large molecules.

What is the purpose of a dryer in a bioprocess?

  1. To remove moisture from a product

  2. To increase the shelf life of a product

  3. To improve the appearance of a product

  4. To reduce the weight of a product


Correct Option: A
Explanation:

Dryers are used to remove moisture from a product, which is necessary to prevent spoilage and to improve the product's stability.

Which of the following is not a type of dryer used in bioprocessing?

  1. Spray dryer

  2. Freeze dryer

  3. Vacuum dryer

  4. Rotary dryer


Correct Option: D
Explanation:

Rotary dryers are not typically used in bioprocessing, as they are not well-suited for the drying of delicate materials.

What is the purpose of a sterilizer in a bioprocess?

  1. To kill microorganisms

  2. To remove impurities from a product

  3. To increase the shelf life of a product

  4. To improve the appearance of a product


Correct Option: A
Explanation:

Sterilizers are used to kill microorganisms, which is necessary to prevent contamination of the product.

Which of the following is not a type of sterilizer used in bioprocessing?

  1. Autoclave

  2. Dry heat sterilizer

  3. Radiation sterilizer

  4. Filtration sterilizer


Correct Option: D
Explanation:

Filtration sterilizers are not typically used in bioprocessing, as they are not well-suited for the sterilization of large volumes of fluid.

What is the purpose of a fermenter in a bioprocess?

  1. To grow microorganisms

  2. To produce a product

  3. To purify a product

  4. To concentrate a product


Correct Option: A
Explanation:

Fermenters are used to grow microorganisms, which are used to produce a variety of products, such as antibiotics, enzymes, and vaccines.

Which of the following is not a type of fermenter used in bioprocessing?

  1. Stirred tank fermenter

  2. Airlift fermenter

  3. Fluidized bed fermenter

  4. Packed bed fermenter


Correct Option: D
Explanation:

Packed bed fermenters are not typically used in bioprocessing, as they are not well-suited for the growth of microorganisms.
