In the Rural Development Plan (2014–2020), the European Commission encouraged the conversion and supported the maintenance of organic farming. Organic olive oil (bioEVOO) production involves the use of environmentally sustainable fertilizers and the recycling of olive pomace (Pom) and olive vegetation waters (VW) to reduce the environmental impact of these wastes. An ecofriendly way to recycle olive wastes is to reuse them to extract bioactive compounds. In this study, the total phenolic compounds content, their profile and dosage, the antioxidant action in oil, pomace, and vegetation water was evaluated when the Trichoderma harzianum M10 was used as a biostimulant in agriculture. Two spectrophotometric tests (2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic) acid (ABTS)) evaluated the antioxidant potential of samples, a spectrophotometric method estimated total phenolic content, and an Ultra-High-Performance Liquid Chromatography (UHPLC)–Orbitrap method evaluated the phenolics profile. Our results showed that the biostimulation improved the antioxidant potential and the total concentration of phenolics in the bioEVOO and bio-pomace (bioPom) samples and mainly enhanced, among all classes of phenolic compounds, the production of the flavonoids and the secoiridoids. Moreover, they demonstrated the Trichoderma action in the mevalonate pathway to produce phenols for the first time. The decisive action of the Thricoderma on the production of phenolic compounds increases the economic value of the waste materials as a source of bioactive compounds useful for the pharmaceutical, cosmetic, and food industries.

一种用于橄榄种植的环保做法，能够增加来自石油加工废料的商业利益。

在《农村发展计划（2014-2020年）》中，欧洲委员会鼓励改建并支持有机农业的维持。有机橄榄油（bioEVOO）的生产涉及使用环保的肥料以及橄榄渣（Pom）和橄榄植物水（VW）的循环利用，以减少这些废物对环境的影响。一种环保的橄榄废料回收方法是将其再利用以提取生物活性化合物。在这项研究中，当哈茨木霉（Trichoderma harzianum）时评估了总酚类化合物的含量，其特征和剂量，在油，果渣和植物水中的抗氧化作用。M10用作农业生物刺激剂。两种分光光度测试（2,2-二苯基-1-吡啶并肼基（DPPH）和2,2'-叠氮双（3-乙基苯并噻唑啉-6-磺酸）酸（ABTS）评估了样品的抗氧化能力，该分光光度法估计了总酚含量，超高效液相色谱（UHPLC）–Orbitrap方法评估了酚类谱。我们的研究结果表明，生物刺激改善了bioEVOO和生物果渣（bioPom）样品中的抗氧化剂潜力和酚类总浓度，并且在所有类别的酚类化合物中，主要增强了类黄酮和类secrididoids的产生。而且，他们展示了木霉首次在甲羟戊酸途径中产生苯酚。的决定性作用 的Thricoderma对生产酚类化合物的提高了废料作为用于药物，化妆品和食品工业有用的生物活性化合物的一个源的经济价值。
