“…For example, pretreatment of bagasse powder using choline acetate (ChOAc) enhanced the tensile strength of the propionylated bagasse composites from 35 MPa to 40 MPa and the elastic moduli from 2.0 GPa to 2.6 GPa compared to the composites made of untreated bagasse powder (Ninomiya et al, 2017). Likewise, Ma et al (2016) compared the pretreatment of corn stalk with a series of pyrrolidonium-based ILs at 90 • C for 30 min and observed 85.94% lignin removal and a reducing sugar yield of 91.81% after enzymatic hydrolysis.…”

Lignocellulosic biomass (LCB) is the most abundantly available bioresource amounting to about a global yield of up to 1. 3 billion tons per year. The hydrolysis of LCB results in the release of various reducing sugars which are highly valued in the production of biofuels such as bioethanol and biogas, various organic acids, phenols, and aldehydes. The majority of LCB is composed of biological polymers such as cellulose, hemicellulose, and lignin, which are strongly associated with each other by covalent and hydrogen bonds thus forming a highly recalcitrant structure. The presence of lignin renders the bio-polymeric structure highly resistant to solubilization thereby inhibiting the hydrolysis of cellulose and hemicellulose which presents a significant challenge for the isolation of the respective bio-polymeric components. This has led to extensive research in the development of various pretreatment techniques utilizing various physical, chemical, physicochemical, and biological approaches which are specifically tailored toward the source biomaterial and its application. The objective of this review is to discuss the various pretreatment strategies currently in use and provide an overview of their utilization for the isolation of high-value bio-polymeric components. The article further discusses the advantages and disadvantages of the various pretreatment methodologies as well as addresses the role of various key factors that are likely to have a significant impact on the pretreatment and digestibility of LCB.

“…Seddon et al 44 reported that the total yield of reducing sugar for potato starch was 54% with the Brønsted-acidic ionic liquids and was 6% with the 1-allyl-3-methylimidazolium chloride at 80 C for 1 h. In this study, a high yield of reducing sugar (72.50%) for potato starch was achieved with the treatment of the mixture of [ In addition, Li et al 45 reported that corn stalk was hydrolyzed in 1-buty-3-methylimidazolium chloride with sulfuric acid as a catalyst at 100 C for 6 h to give 37% of total reducing sugar. Ma et al 46 demonstrated that corn stalk was treated by Nmethyl-2-pyrrolidonium methanesulfonate, N-methyl-2pyrrolidonium hydrogen sulfate and N-methyl-2pyrrolidonium chloride at 90 C for 30 min, and the resulting yield of reducing sugar was 23.51%, 22.26% and 20.19%, respectively. In this study, a high yield of reducing sugar for corn stalk was achieved at 18.80% for 6 h (Fig.…”

The ionic liquids have emerged as new solvents and catalysts for processing biomass to value added chemicals and fuels. This review will present the recent developments in applications of ionic liquids in lignocellulosic biomass pretreatments, depolymerization, biodiesel synthesis, dehydration of carbohydrates to renewable feedstock chemicals as well as further transformations of biomass derived feedstocks such as furfural, 5‐hydroxymethylfurfural and levulinic acid to value added chemicals. In addition, the recycling of ionic liquids used in biomass processing is also discussed in the review.
