Rotating | Rotating drum bioreactors mix intermittently without forced aeration, operating on continuous or semi-continuous mode. A rotating drum bioreactor is a horizontal cylinder. The drum is semi-filled with a bed of substrate. The fermented bed cannot be too high and this creates good oxygen and carbon dioxide transfer. Temperature control also depends on the mixing effect on the solid substrate. | ||

In order to maximize product yield, downstream strategies play an important role. The choice of downstream strategy is dependent of the type of product. For instance, if the product containts cellulase than the following downstream-based strategies can be used:<ref>{{Cite book|author=Darshan M.
