Witryna1 sty 2007 · The choice of bioreactors for immobilized cells is dependent on the immobilization technique, cell metabolism, the shear rate and the mass transfer requirement. The most popular immobilized cell bioreactors employed for various applications include the stirred tank bioreactor, packed-bed bioreactor, fluidized-bed … 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).
A bioreactor refers to any manufactured device or system that supports a biologically active environment. In one case, a bioreactor is a vessel in which a chemical process is carried out which involves organisms or biochemically active substances derived from such organisms. This process can either be aerobic or anaerobic. These bioreactors are commonly cylindrical, ranging in size from lit… Witryna12 gru 2011 · Figures.
