WitrynaIt is difficult in immobilized cell bioreactors to control the physiological state of microorganisms, and due to the process variability and flexibility can not be ensured. Immobilized cell bioreactors divide into stirred tank, fixed bed, fluidized bed, moving bed, packed bed and membrane reactors. WitrynaContinuous ethanol production in a three stage horizontal tank bioreactor (HTR) by yeast cells entrapped in Ca-alginate was about 30% higher than in a vertical type of bioreactor and reached 31 kg/(m3 · h) at 95% glucose utilization. Maximum ethanol productivity obtained was 41.2 kg/(m3 · h), however, with 38% of the glucose fed to the HTR … WitrynaA previously developed immobilization technique involving agar as matrix is investigated further in penicillin produced by P. chrysogenum ATCC 10238 at reactor level.

WitrynaThere are two ways of separating SRT from HRT: using the immobilization of cells and keeping cells in the reactor such that cell washout can be avoided, for instance, using … Witryna12 lis 2014 · Fluidised bed reactors In fluidized-bed fermenters the cells are immobilized on or in small particles. The use of small particles increases the surface area for cell immobilization and mass transfer. Because the particles are small and light, they can be easily made to flow with the liquid (ie. fluidised).
