Ultrafast fractionation of lignocellulosic biomass by microwave-assisted deep eutectic solvent pretreatment
Abstract
Deep eutectic solvents (DESs) have received increasing attention in recent years as designer solvents for bioprocessing. In this study, ultrafast microwave-assisted DES pretreatment was developed for lignocellulose fractionation. The pretreatment was conducted for 45 s with microwave irradiation at 800 W using a DES composed of choline chloride and lactic acid (ChCl: LA). The results indicated that such pretreatment was highly effective in removing lignin and xylan while retaining most of cellulose in the pretreated solids. The ultrafast fractionation increased the cellulose digestibility by 2-5 folds. Switchgrass gave a similar glucose yield to corn stover but experienced less cellulose loss during the pretreatment. Miscanthus was also substantially fractionated but showed lower digestibility than switchgrass and corn stover. Lignin was readily recoverable with relatively high purity from all the pretreatment liquor. Our study demonstrated an innovative ultrafast pretreatment process with superior effectiveness for biomass fractionation and cellulose digestibility improvement as well as lignin extraction.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
