Olive oil production generates high amounts of liquid and solid wastes. For a long time, such complex matrices were considered only as an environmental issue, due to their polluting properties. On the other hand, olive mill wastes (OMWs) exert a positive effect on plant growth when applied to soil due to the high content of organic matter and mineral nutrients. Moreover, OMWs also exhibit antimicrobial activity and protective properties against plant pathogens possibly due to the presence of bioactive molecules including phenols and polysaccharides. This review covers the recent advances made in the identification, isolation, and characterization of OMW-derived bioactive molecules able to influence important plant processes such as plant growth and defend against pathogens. Such studies are relevant from different points of view. First, basic research in plant biology may benefit from the isolation and characterization of new biomolecules to be potentially applied in crop growth and protection against diseases. Moreover, the valorization of waste materials is necessary for the development of a circular economy, which is foreseen to drive the future development of a more sustainable agriculture.
橄榄油生产会产生大量的液体和固体废弃物。长期以来，由于其污染特性，这类复杂的基质仅被视为一个环境问题。另一方面，橄榄果渣废弃物（OMWs）施用于土壤时，因其高含量的有机质和矿质养分，对植物生长具有积极作用。此外，OMWs还表现出抗菌活性以及对植物病原体的保护特性，这可能归因于包括酚类和多糖在内的生物活性分子的存在。本综述涵盖了在鉴定、分离和表征源自OMWs的生物活性分子方面取得的最新进展，这些分子能够影响重要的植物过程，如植物生长和抵御病原体。此类研究从不同角度来看都具有重要意义。首先，植物生物学的基础研究可能会受益于新生物分子的分离和表征，这些新生物分子有望应用于作物生长和疾病防治。此外，废弃物的资源化利用对于循环经济的发展至关重要，而循环经济预计将推动未来更可持续农业的发展。
