What tends to happen to cells in filamentous cells like actinomycetes and fungi?
What tends to happen to cells in filamentous cells like actinomycetes and fungi?
- They form a gradient concentration of the product from the inside to the outside.
- They tend to aggregate and only those at the periphery of the clump grow. (correct)
- They avoid clumping by growing in the center of the clump.
- They tend to grow uniformly throughout the clump.
How is the avoidance of clumps and the production of loosely organized cells achieved in the airlift fermentor?
How is the avoidance of clumps and the production of loosely organized cells achieved in the airlift fermentor?
- By circulating the broth in an external membrane in contact with water. (correct)
- By maintaining a high concentration of components in the fermentation broth.
- By subjecting the broth to dialysis.
- By applying reduced pressure to remove volatile end products.
Why is feedback inhibition a concern in high concentrations of fermentation broth components?
Why is feedback inhibition a concern in high concentrations of fermentation broth components?
- It accelerates fermentation.
- It enhances production.
- It limits production easily. (correct)
- It promotes cell growth.
