Question

Which one of these reasons would be taken into consideration when a continuous culture bioreactor is used?

• A. The manpower is less
• B. Need to grow the organisms quickly
• C. The transgenic organism is a rod shaped bacteria
• D. The transgenic organism take long time to achieve growth phase

Answer 1

The correct option is D The transgenic organism take long time to achieve growth phase

Bioreactors are expensive units to maintain. An organism that take a long time to reach growth phase, makes out for an expensive investment if the batch culture is used. Every cycle of sterilization and inoculation of the culture is very expensive. Instead a continuous culture where nutrients can be added at regular intervals, while removing a part of the final culture makes more sense, monetarily.
