Stirred tank Bioreactor

The aspect ratio of a stirred tank bioreactor is usually between

• 3-5

• 2-4

• 4-6

• 2-6

In stirred tank bioreactors or in short stirred tank reactors (STRs), the air is added to the culture medium under pressure through a device called

• Impellar

• sparger

• Filterdisc

• Port

Role of impellar

• Agitation

• Aeration

• pH maintenance

• passage of medium

Height to diameter ratio of bioreactor

• Academy ratio

• Screen ratio

• Aspect Ratio

• None of the above
