Ideal reactor operation

Question 1

What are the 3 principle modes of bioreactor operation?

Answer 1

Batch, fed-batch and operation

Question 2

How can characteristics such as the final biomass, substrate, product concentrations and the time
required for conversion can be determined for different reactor operating schemes using which of equation?

Answer 2

Mass balance

Question 3

What type of system is a batch process

Answer 3

Closed system

Substrate is added at the beginning of the process and products removed only at the end

liquid volume stays constant

Question 4

Are aerobic reactions batch operations?

Answer 4

They’re not batch operations in the strictest sense; the low solubility of oxygen in aqueous media means that it must be supplied continuously
while carbon dioxide and other off-gases are removed.

Question 5

Consider the batch reactor mass balance equation for enzyme reactions

Answer 5

Question 6

Find an equation for tb - batch reaction time required to reduce the substrate concentration from s0
to sf

Answer 6
