(b) Draw a well labelled diagram of simple stirred - tank
bioreactor
(c) How does a simple stirred - tank' bioreactor differ from
sparged stirred - tank' bioreactor?

Dear student

Please find the solution below
1 
Bioreactor is an apparatus in which a biological reaction or
process is carried out The chemical reactions take place in
presence of microorganisms in this bioreactor It can be aerobic or
anaerobic Sterile air (oxygen bubble) is poured inside a bioreactor
to prevent the cake like layer of biomass over the liquid
Bioreactor helps to mix the nutrients well with water and keeps the
fermentation homogeneous The condition such as temperature,
pH, dissolved oxygen levels and agitation rate varies according to
the type of microorganisms and bioreactor are used

Simple stirred bioreactor
Sparged stirred bioreactor

The stirrer facilitates even mixing and oxygen availability
throughout the bioreactor
Air is bubbled through the reactor, there is an increased
surface area for oxygen transfer, as the bubbles increase the
oxygen transfer area
