Abstract

Addressing global environmental challenges and meeting the escalating energy demands stand as two pivotal issues in the current landscape. Lignocellulosic biomass emerges as a promising renewable bio-energy source capable of fulfilling the world’s energy requirements on a large scale. One of the most important steps in lowering reliance on fossil fuel and lessening environmental effect is turning lignocellulosic biomass into biofuel. As carbon–neutral substitutes for traditional fuel, biofuel offer a solution to environmental concerns compared to conventional fuel. Effective utilization of lignocellulosic biomass is imperative for sustainable development. Ongoing research focuses on exploring the potential of various microorganisms and their co-interactions to synthesize diverse biofuels from different starting materials, including lignocellulosic biomass. Co-culture techniques demonstrate resilience to nutrient scarcity and environmental fluctuations. By utilising a variety of carbon sources, microbes can enhance their adaptability to environmental stressors and potentially increase productivity through their symbiotic interactions. Furthermore, compared to single organism involvement, co-interactions allow faster execution of multistep processes. Lignocellulosic biomass serves as a primary substrate for pre-treatment, fermentation, and enzymatic hydrolysis processes. This review primarily delves into the pretreatment, enzymatic hydrolysis process and the biochemical pathways involved in converting lignocellulosic biomass into bioenergy.

最大限度地提高微生物活性和协同作用，促进木质纤维素生物质的生物燃料生产

应对全球环境挑战和满足日益增长的能源需求是当前的两大关键问题。木质纤维素生物质是一种前景广阔的可再生生物能源，能够大规模满足世界能源需求。要降低对化石燃料的依赖，减少对环境的影响，最重要的步骤之一就是将木质纤维素生物质转化为生物燃料。与传统燃料相比，生物燃料作为传统燃料的碳中性替代品，为环境问题提供了一种解决方案。有效利用木质纤维素生物质是可持续发展的当务之急。目前的研究重点是探索各种微生物及其协同作用的潜力，以便从不同的起始材料（包括木质纤维素生物质）合成多种生物燃料。共培养技术显示出对养分匮乏和环境波动的适应能力。通过利用各种碳源，微生物可以增强对环境压力的适应能力，并可能通过共生相互作用提高生产力。此外，与单个生物参与相比，共生相互作用可以更快地执行多步骤过程。木质纤维素生物质是预处理、发酵和酶水解过程的主要基质。本综述主要探讨将木质纤维素生物质转化为生物能源所涉及的预处理、酶水解过程和生化途径。

期刊介绍： Research papers must make a significant and original contribution to microbiology and be of interest to a broad readership. The results of any experimental approach that meets these objectives are welcome, particularly biochemical, molecular genetic, physiological, and/or physical investigations into microbial cells and their interactions with their environments, including their eukaryotic hosts. Mini-reviews in areas of special topical interest and papers on medical microbiology, ecology and systematics, including description of novel taxa, are also published. Theoretical papers and those that report on the analysis or ''mining'' of data are acceptable in principle if new information, interpretations, or hypotheses emerge.
