Bio Fermenter, Mechanical Stirring, Glass Bioreactor, and Laboratory Fermentor

Question

Accepted Answer

Question 1: What is the main purpose of a bio fermenter?

A bio fermenter is used to create an optimal environment for the growth and metabolic activities of microorganisms or cells. It allows for controlled conditions to produce desired biochemicals or biomass.

Question 2: How does mechanical stirring in a bio fermenter help?

Mechanical stirring ensures uniform distribution of nutrients, oxygen, and heat throughout the fermentation broth. This homogeneity promotes efficient growth and metabolism of the organisms.

Question 3: What are the advantages of a glass bioreactor in the laboratory?

The transparency of glass allows for direct visual monitoring of the fermentation process. It is also chemically resistant and easy to clean and sterilize.

Question 4: Can a laboratory fermentor be used for different types of fermentations?

Yes, a laboratory fermentor can be adapted for various types of microbial or cell-based fermentations by adjusting parameters such as temperature, pH, and aeration.

Question 5: How is the oxygen supply managed in a bio fermenter?

Oxygen can be supplied through aeration systems, spargers, or by using oxygen-permeable membranes. The amount and method of oxygen supply depend on the oxygen requirements of the organisms.

Question 6: What kind of samples can be processed in a glass bioreactor?

It can handle a wide range of samples, including microbial cultures, cell suspensions, and plant cell cultures.

Question 7: How often does a mechanical stirring system need maintenance?

The frequency of maintenance depends on usage, but typically it should be inspected and serviced regularly to prevent breakdowns and ensure consistent performance.

Question 8: How is the pH controlled in a laboratory fermentor?

pH is controlled by adding acids or bases automatically or manually based on pH sensor readings. Buffer solutions may also be used to stabilize the pH.

Question 9: Are there size limitations for laboratory fermentors?

Yes, laboratory fermentors come in various sizes, but they are generally smaller than industrial-scale fermenters and are designed to meet the needs of research and small-scale production.

Question 10: How can one ensure sterility in a glass bioreactor and laboratory fermentor?

This can be achieved through proper cleaning and sterilization protocols, using autoclaves or chemical sterilants. Maintaining a clean working environment and aseptic techniques during operation is also crucial.
