“…Enzymolysis at high solid loading can contribute to gaining high sugars concentration while cutting the cost of a lignocellulose biorefinery due to fewer devices, less energy and water consumption. However, high solid loading may definitely reduce the enzymolysis efficiency because of high viscosity, poor mass transfer and lower contact between biomass and cellulase . Based on the superiorities of AHP‐ILW pretreatment, further study of enzymolysis with high solid loading is essential.…”

“…It was speculated that fermentation inhibitors such as various organic acids accumulated gradually during the process of SScF and the high viscosity could also cause loss of efficiency. An effective method for high solids fed‐batch enzymolysis of sugarcane bagasse based on system viscosity changes has been developed and could alleviate the high viscosity problem . Therefore, the optimization of SScF processes such as with fed‐batch schemes at high solid loadings is worth further study.…”

“…Liu et al [30], for example, reported laboratory (small scale 250 mL) studies on batch-fed saccharification of sugarcane bagasse, and achieved 135 g/L glucose (13 % w/v) using cellulase loadings of 8.5 FPU/g substrate. Their pretreatment required high levels of hot alkali (equivalent to 200 kg NaOH per tonne bagasse).…”

“…Furthermore, after a certain level of hydrolysis is achieved, a pulsed feed of new pretreated biomass can be administered to the reactor. Such a fed-batch process can be effective only when care is taken that the new batch of hygroscopic biomass does not create enzyme mass transfer issues (Liu et al, 2015). With phase angle data from our rheological testing, along with further optimization, it will be possible to identify a suitable time for administering the new batch.…”
