摘要

微藻为解决可持续能源和营养安全这两个最紧迫的全球挑战提供了一个独特的、双重用途的平台。微藻生长迅速，脂质含量高，对土地和水的需求最小，为生物柴油和omega-3提供了可扩展和可持续的来源。这篇综述首次对整个微藻生产链进行了全面分析，从培养到下游转化，特别关注生物柴油和omega-3途径。采用预定义的纳入/排除标准，对Elsevier、Wiley和b施普林格（2016-2024）进行了结构化文献综述。根据研究设计、数据透明度和测量方法评估偏倚风险。主要研究结果表明，回旋池和光生物反应器提供了可扩展性和生产力之间的最佳权衡。超临界CO2和微波辅助萃取技术在提高生物柴油产量和omega-3质量方面优于传统的溶剂方法。应激诱导的营养限制策略（如氮消耗）在没有基因修饰的情况下持续促进脂质积累。将种植与城市或工业废水相结合，降低了运营成本，同时有助于减少碳排放和养分循环。尽管存在经济和扩大规模的障碍，例如光生物反应器的高资本成本和光穿透效率低下，但最近的创新包括杂交栽培系统，适应性进化和副产物增值显示出克服这些限制的强大潜力。从单一微藻生物质流中同时生产生物柴油和omega-3也直接符合多个可持续发展目标（sdg）。本文的见解为在全球生物经济中推进这些双价值脂质流从微藻向可扩展，政策一致和市场响应的实施提供了决策支持基础。

Microalgae for sustainable biodiesel and omega-3: A comprehensive review of production, processing, and implementation

Microalgae present a unique, dual-purpose platform for addressing two of the most urgent global challenges: sustainable energy and nutritional security. With rapid growth, high lipid content, and minimal land and water requirements, microalgae offer a scalable and sustainable source for both biodiesel and omega-3. This review is the first to provide a comprehensive analysis of the entire microalgae production chain, from cultivation to downstream conversion, focused specifically on biodiesel and omega-3 pathways. A structured literature review was conducted across Elsevier, Wiley, and Springer (2016–2024), using predefined inclusion/exclusion criteria. Risk of bias was assessed based on study design, data transparency, and measurement methods. Key findings reveal that raceway ponds and photobioreactors offer the best trade-off between scalability and productivity. Supercritical CO₂ and microwave-assisted extraction techniques outperform conventional solvent methods in enhancing both biodiesel yield and omega-3 quality. Stress-induced nutrient limitation strategies (e.g., nitrogen depletion) consistently boosted lipid accumulation without genetic modification. Integrating cultivation with municipal or industrial wastewater reduced operational costs while contributing to carbon mitigation and nutrient recycling. Despite economic and scale-up barriers, such as high photobioreactor capital costs and light penetration inefficiencies, recent innovations including hybrid cultivation systems, adaptive evolution, and co-product valorization demonstrate strong potential to overcome these limitations. The simultaneous production of biodiesel and omega-3 from a single microalgae biomass stream also aligns directly with multiple Sustainable Development Goals (SDGs). The insights herein offer a decision-support foundation for advancing these dual-value lipid streams from microalgae toward scalable, policy-aligned, and market-responsive implementation in the global bioeconomy.

期刊介绍： The mission of Renewable and Sustainable Energy Reviews is to disseminate the most compelling and pertinent critical insights in renewable and sustainable energy, fostering collaboration among the research community, private sector, and policy and decision makers. The journal aims to exchange challenges, solutions, innovative concepts, and technologies, contributing to sustainable development, the transition to a low-carbon future, and the attainment of emissions targets outlined by the United Nations Framework Convention on Climate Change. Renewable and Sustainable Energy Reviews publishes a diverse range of content, including review papers, original research, case studies, and analyses of new technologies, all featuring a substantial review component such as critique, comparison, or analysis. Introducing a distinctive paper type, Expert Insights, the journal presents commissioned mini-reviews authored by field leaders, addressing topics of significant interest. Case studies undergo consideration only if they showcase the work's applicability to other regions or contribute valuable insights to the broader field of renewable and sustainable energy. Notably, a bibliographic or literature review lacking critical analysis is deemed unsuitable for publication.
