Stirred Tank Bioreactors

Electro- spray bioreactors Trickle- bed bioreactor Stirred Tank Bioreactor .. 8 Trickle bed: another variation of the packed bed, fluid is sprayed onto the top of the packing and trickles down through the bed. Air is introduced at the base, because liquid is not continuous throughout the column, so air moves easily around the packing.
