Fig. 5From: Kinetic modeling of countercurrent saccharificationEffect of enzyme-addition location on conversion in the eight-stage countercurrent system at enzyme loadings of a 2 mg/g and b 5 mg/g using α-cellulose as substrate. Operation time is 200 days. Other conditions in this simulation are set to be the same as the experimental conditions. Simulation data are presented by the markers and the lines are added to show the changing trendBack to article page
