Immobilized cell reactors
WitrynaWhen the immobilized cell reactor is operated in the horizontal position, CO2 holdup is decreased, as is evidenced by an increase in liquid holdup. However, the horizontal and vertical reactors showed almost identical substrate profiles at constant cell densities. In addition, under prolonged operation, the performance of the horizontal reactor ... WitrynaThe kinetics of immobilized cell systems in ethanol production have been studied in a packed bed-reactor. Ethanol production and the respiration quotient (RQ) were at a maximum at a dilution rate of 0.16/h. The reactor was operated under steady-state conditions for 30 d at the dilution rate 0.16/h.

WitrynaImmobilized cell systems are pertinent to fermentation because of reactor performance advantages that immobilized cells provide over freely suspended cultures, easy separation of the biomass from the liquid and easy product recovery, and specific metabolic improvements or products created upon immobilization. Cell immobilization … WitrynaAn immobilized cell reactor is classified as a continuous biological system that may follow either plug flow theory or fluidized-bed theory depending on the mode of operation. IV.J.3 Applications. The use of immobilized cell systems is applicable to all fermentation schemes and is being researched extensively for the production of alcohols ...
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 … http://www.pharmatips.in/Articles/Biology/Biotechnology/Immobilization-Of-Plant-Cells.aspx
