Table 2 Effect of cellulase recycling on the overall glucose yields and total amounts of produced glucose (mean ± standard deviation) from the enzymatic hydrolysis of hydrothermally-pretreated EFBs

From: Cellulase recycling in high-solids enzymatic hydrolysis of pretreated empty fruit bunches

Mode of  the two-round enzymatic hydrolysis Hydrolysis round Cellulase loading (FPU/g glucan) Glucose yield (% of theoretical max.) Total amount of glucose produced (g)c
Separate hydrolysis without cellulase recycling R1a 20 78.2 ± 0.1 3.70 ± 0.00
R2b 20 78.2 ± 0.1
Cellulase recycling R1a 40 98.7 ± 0.8 2.79 ± 0.15
R2b 0 19.3 ± 5.7
Cellulase recycling with the additional treatments R1a 40 98.7 ± 0.8 3.94 ± 0.06
R2b 0 68.0 ± 1.8
