Valorization of bamboo biomass using combinatorial pretreatments

Abstract

Current studies concerning liquid hot water pretreatment (LHWP) usually focus on cellulose saccharification or hemicellulose conversion, while the appropriate extraction and utilization of LHWP-induced lignin have not been addressed.

Revisiting organosolv strategies for sustainable extraction of valuable lignin: the CoffeeCat process

“…This result is very promising as it supports the current trend to use combined pretreatments for biomass full valorization. 107 Moreover, the FTIR spectra of the residual solid fraction evidenced the isolation of a residual le enzymatic hydrolysis lignin (see ESI, Fig. S5 †).…”

Evaluating the mechanism of milk protein as an efficient lignin blocker for boosting the enzymatic hydrolysis of lignocellulosic substrates

“…32,33 However, since DO 15 was discontinued by the supplier, researchers have discovered an alternative dye Direct Red 28 (DR28) with similar properties to DO 15 that could be used to evaluate the cellulose accessibility of pretreated substrate. 34,35 A modified Congo red (Direct Red 28) assay based on the literature was used to assess the cellulose accessibility of the pretreated and protein pre-adsorbed bamboo residues. 36 The absorption of Congo red onto the bamboo substrates was carried out in a 50 ml conical flask with a substrate loading of 1% (w/v).…”

Direct Extraction of Uniform Lignin Microspheres from Bamboo Using a Polyol-Based Deep Eutectic Solvent

“…In this regard, lignocellulosic biomass conversion has aroused copious attention due to its wide distribution, sustainability, low cost, and capability to produce various products . Lignocellulose is mainly composed of polysaccharides (cellulose and hemicellulose) and an aromatic biopolymer (lignin) . As well acknowledged, cellulose and hemicellulose have many successful applications such as pulping, bioethanol, nanomaterial, prebiotic oligomers, and others .…”

“…2 Lignocellulose is mainly composed of polysaccharides (cellulose and hemicellulose) and an aromatic biopolymer (lignin). 3 As well acknowledged, cellulose and hemicellulose have many successful applications such as pulping, bioethanol, nanomaterial, prebiotic oligomers, and others. 4 However, the utilization of lignin is still in its infancy, which is most often either combusted for heat recovery or just discharged.…”
