Q. How is a continuous culture system maintained in bioreactors and why?

Q. Continuous culture has cells in which of the following growth phases?

1. Stationary phase
2. Lag phase
3. Both a and b
4. Exponential phase

Q. Using continuous culture for growing recombinant cells helps to obtain

1. smaller biomass of cells
2. higher yields of desired proteins
3. larger biomass of cells
4. both b and c

Q. How is a continuous culture system maintained in bioreactors and why?

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

1. The transgenic organism take long time to achieve growth phase
2. The transgenic organism is a rod shaped bacteria
3. Need to grow the organisms quickly
4. The manpower is less

Q. Based on the method of culturing, bioreactors are either batch cultures or continuous cultures. If a transgenic bacteria shows quick growth cycle, what would be the most pragmatic method to produce it on an industrial scale?

1. Open Culture method
2. Closed Culture method
3. Single Batch culture method
4. Either of the three will give efficient results
