Abstract

Lignocellulosic biomass has the potential to be transformed into platform chemicals, biofuels, and materials. This work considered an undisclosed 1-ethyl-2-methylimidazolium glutamate ([Emim]Glu) ionic liquid from the class of amino acid-based ionic liquids for effienct deconstruction of biomass (previously only separation of lignin and holocellulose has been reported) into three components (lignin, cellulose, and hemicellulose) of biomass and further release of glucose that owed for bioethanol production. Using [Emim]Glu, bamboo biomass was successfully deconstructed, leading to high component separation efficiency in mild conditions (120 °C, 19 h). A remarkable 65.2 % cellulose recovery, 60.1 % lignin yield, and 7.2 % hemicellulose recovery were attained by the optimized process. After 8 h of saccharification, the regenerated cellulose-rich fraction produced up to 86 % glucose, demonstrating exceptional enzymatic digestibility. While FTIR, HPLC, Raman spectroscopy and CHNS etc confirmed component separation. Additionally, [Emim]Glu showed excellent recyclability with negligible performance loss. These findings show that [Emim]Glu is a green and effective solvent for the fractionation of biomass and the production of glucose, with promising potential for the development of sustainable bioethanol.

[Emim]Glu离子液体作为木质纤维素生物质分解为生物基材料的溶剂的评价

木质纤维素生物质具有转化为平台化学品、生物燃料和材料的潜力。这项工作考虑了一种未公开的1-乙基-2-甲基咪唑谷氨酸（[Emim]Glu）离子液体，它是氨基酸基离子液体，用于有效地分解生物质（以前只报道了木质素和纤维素的分离）为生物质的三种成分（木质素、纤维素和半纤维素），并进一步释放用于生物乙醇生产的葡萄糖。使用[Emim]Glu，成功地解构了竹子生物量，在温和条件下（120°C, 19 h）实现了高组分分离效率。优化后的纤维素回收率为65.2%，木质素收率为60.1%，半纤维素回收率为7.2%。糖化8小时后，再生的富含纤维素的部分产生高达86%的葡萄糖，表现出特殊的酶消化率。FTIR、HPLC、拉曼光谱、CHNS等均证实了组分的分离。此外，[Emim]Glu具有出色的可回收性，性能损失可以忽略不计。这些发现表明，[Emim]Glu是一种绿色有效的生物质分馏和葡萄糖生产溶剂，在开发可持续生物乙醇方面具有广阔的潜力。

期刊介绍： Biomass & Bioenergy is an international journal publishing original research papers and short communications, review articles and case studies on biological resources, chemical and biological processes, and biomass products for new renewable sources of energy and materials. The scope of the journal extends to the environmental, management and economic aspects of biomass and bioenergy. Key areas covered by the journal: • Biomass: sources, energy crop production processes, genetic improvements, composition. Please note that research on these biomass subjects must be linked directly to bioenergy generation. • Biological Residues: residues/rests from agricultural production, forestry and plantations (palm, sugar etc), processing industries, and municipal sources (MSW). Papers on the use of biomass residues through innovative processes/technological novelty and/or consideration of feedstock/system sustainability (or unsustainability) are welcomed. However waste treatment processes and pollution control or mitigation which are only tangentially related to bioenergy are not in the scope of the journal, as they are more suited to publications in the environmental arena. Papers that describe conventional waste streams (ie well described in existing literature) that do not empirically address ''new'' added value from the process are not suitable for submission to the journal. • Bioenergy Processes: fermentations, thermochemical conversions, liquid and gaseous fuels, and petrochemical substitutes • Bioenergy Utilization: direct combustion, gasification, electricity production, chemical processes, and by-product remediation • Biomass and the Environment: carbon cycle, the net energy efficiency of bioenergy systems, assessment of sustainability, and biodiversity issues.
