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).

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.

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… 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 …
