• Bioreactor — Wikipedia Republished // WIKI 2

    On the basis of mode of operation, a bioreactor may be classified as batch, fed batch or continuous ( a continuous stirredtank reactor model). An example of a continuous bioreactor is the chemostat. Organisms growing in bioreactors may be submerged in liquid medium or may be attached to the surface of a solid medium.
