Summary A special tubular closed loop fermenter was used in order to simulate the particular mixing condition of a large scale recycle fermenter. Some mixing parameters of the system are characerized. During continuous cultivation ofCandida tropicalis on n-paraffin as a substrate the biomass yield with respect to carbon and oxygen increased, when a controlled oxygen limit was imposed on the culture. Mixing in the closed loop fermenter generates undamped short period oscillations in the respiration activity, in the dissolved oxygen tension and in the actual ATP content of the culture. These oscillations likely represent oscillations of allosteric feedback loops which manifest themselves by some synchronising action of the particular environmental transients in the closed loop fermenter.
