The process involves growing the cells in
a fermenter, immobilising them on a gel, and then placing them in
the reactor.
Question
Although the enzyme is stable to
propeneonitrile, the reagent is fed continuously to the batch
reactor in order to keep its concentration down. Can you suggest
a reason for this procedure?
Question
The yield on propenonitrile is nearly
100 %. What waste is produced in this process?
Answer
The nutrients are consumed in the fermentation, so some fermentation
medium and spent cells are waste.
