Extracted text: Choose all of the correct statements regarding harvesting from a bioreactor. O Harvesting occurs after downstream processing of the product. O None of these options are true. The harvest time will ideally occur when cells have changed their metabolism. O The harvest time will ideally occur in late stationary phase for growth-associated products. O The harvest time will ideally occur in stationary phase just before reaching the dealth phase and the cell concentration begins to decrease.


Extracted text: Choose all that are correct regarding impeller type choice in bioreactors. Marine type impellers are ideal for shear sensitive mammalian cells. Marine type impellers are ideal for less shear sensitive yeast cells. O One function of the impeller is to mix the contents of the bioactor (e.g., nutirents). None of these options are true. O Impeller type choice depends on the shear sensitivity of the target cells and the solution viscosity.
