With the increasing demand for fossil fuels, decreasing fossil fuel reserves and deteriorating global environment, humanity urgently need to explore new clean and renewable energy to replace fossil fuel resources. Biodiesel, as an environmentally friendly fuel that has attracted considerable attention because of its renewable, biodegradable, and non-toxic superiority, seems to be a solution for future fuel production. Tobacco ( L.), an industrial crop, is traditionally used for manufacturing cigarettes. More importantly, tobacco seed is also widely being deemed as a typical inedible oilseed crop for the production of second-generation biodiesel. Advancements in raw material and enhanced production methods are currently needed for the large-scale and sustainable production of biodiesel. To this end, this study reviews various aspects of extraction and transesterification methods, genetic and agricultural modification, and properties and application of tobacco biodiesel, while discussing the key problems in tobacco biodiesel production and application. Besides, the proposals of new ways or methods for producing biodiesel from tobacco crops are presented. Based on this review, we anticipate that this can further promote the development and application of biodiesel from tobacco seed oil by increasing the availability and reducing the costs of extraction, transesterification, and purification methods, cultivating new varieties or transgenic lines with high oilseed contents, formulating scientific agricultural norms and policies, and improving the environmental properties of biodiesel.
随着对化石燃料需求的不断增加、化石燃料储备的减少以及全球环境的恶化，人类迫切需要探索新的清洁和可再生能源来替代化石燃料资源。生物柴油作为一种环保型燃料，因其可再生、可生物降解和无毒的优势而备受关注，似乎是未来燃料生产的一种解决方案。烟草是一种经济作物，传统上用于制造香烟。更重要的是，烟草种子也被广泛视为用于生产第二代生物柴油的典型非食用油料作物。目前，大规模可持续生产生物柴油需要在原料和生产方法上取得进展。为此，本研究综述了烟草生物柴油的提取和酯交换方法、遗传和农业改良、性质及应用等各个方面，同时讨论了烟草生物柴油生产和应用中的关键问题。此外，还提出了从烟草作物生产生物柴油的新途径或新方法。基于此综述，我们预计，通过提高提取、酯交换和纯化方法的可用性并降低其成本，培育高含油量的新品种或转基因品系，制定科学的农业规范和政策，以及改善生物柴油的环境特性，这可以进一步促进烟草籽油生物柴油的开发和应用。
