Abstract

This study explored nanoparticle (NP)-assisted bioethanol production from seven lignocellulosic biomass (LCB) types: corn cob (Zea mays), wheat bran (Triticum aestivum), sugarcane (Saccharum officinarum), magnolia (Magnolia grandiflora), London plane (Platanus acerifolia), chestnut (Castanea sativa), and wire grass (Aristida). A deashing step was employed to address the high ash content of the biomass utilizing citric acid trisodium dihydrate salt followed by autoclaving at 120°C for 4 h. The treated biomass was hydrolyzed using cerium-doped iron oxide (CeFe₃O₄) nanoparticles (NPs). Corn cob hydrolysis without pretreatment yielded the highest concentrations of glucose (33.5 ± 0.82 g/L) and xylose (26.7 ± 0.98 g/L). Subsequently, fermentation with Saccharomyces cerevisiae produced the highest ethanol concentration of 28.8 ± 1.63 g/L and a productivity of 2.39 ± 0.13 g/L/h within 12 h. CeFe₃O₄ NPs also, facilitated xylose metabolism and were recyclable. This method enhances biomass conversion efficiency, making bioethanol production more cost-effective and environmentally friendly.

纳米颗粒辅助从各种木质纤维素生物质生产生物乙醇

本研究探索了纳米颗粒（NP）辅助生物乙醇生产的7种木质纤维素生物质（LCB）类型：玉米芯（Zea mays），麦麸（Triticum aestivum），甘蔗（Saccharum officinarum），木兰（magnolia grandflora），伦敦树（Platanus acerifolia），板栗（Castanea sativa）和铁丝草（Aristida）。采用柠檬酸二水合三钠盐对生物质进行脱灰处理，然后在120℃下蒸压4 h。采用掺铈氧化铁（CeFe3O4）纳米颗粒（NPs）水解处理后的生物质。未经预处理的玉米芯水解得到最高浓度的葡萄糖（33.5±0.82 g/L）和木糖（26.7±0.98 g/L）。随后，用酿酒酵母发酵12 h，乙醇浓度最高，为28.8±1.63 g/L，产率为2.39±0.13 g/L/h。CeFe3O4 NPs还促进木糖代谢，可回收利用。这种方法提高了生物质转化效率，使生物乙醇生产更具成本效益和环境友好性。

期刊介绍： The International Journal of Energy Research (IJER) is dedicated to providing a multidisciplinary, unique platform for researchers, scientists, engineers, technology developers, planners, and policy makers to present their research results and findings in a compelling manner on novel energy systems and applications. IJER covers the entire spectrum of energy from production to conversion, conservation, management, systems, technologies, etc. We encourage papers submissions aiming at better efficiency, cost improvements, more effective resource use, improved design and analysis, reduced environmental impact, and hence leading to better sustainability. IJER is concerned with the development and exploitation of both advanced traditional and new energy sources, systems, technologies and applications. Interdisciplinary subjects in the area of novel energy systems and applications are also encouraged. High-quality research papers are solicited in, but are not limited to, the following areas with innovative and novel contents: -Biofuels and alternatives -Carbon capturing and storage technologies -Clean coal technologies -Energy conversion, conservation and management -Energy storage -Energy systems -Hybrid/combined/integrated energy systems for multi-generation -Hydrogen energy and fuel cells -Hydrogen production technologies -Micro- and nano-energy systems and technologies -Nuclear energy -Renewable energies (e.g. geothermal, solar, wind, hydro, tidal, wave, biomass) -Smart energy system
