摘要: AbstractThe viscous nature of fermentation broths has a marked effect on many parameters and process conditions within the bioreactor, often resulting in changes microbial behavior product formation. Although processes that involve significant broth rheology have attracted much research interest, problems still remain. Particular difficulties remain relation to where develops pronounced non-Newtonian characteristics.This article reviews some models developed describe these fluids their limitations; bioreactor types employed mode operation; encountered because fluids, for example, monitoring control; gradients found such systems. To illustrate above, four specific are described detail — production filamentous biomass (SCP) three extracellular polysaccharides, xanthan, pullulan, scleroglucan.
