Reuse of olive mill wastewaters (OMWWs) in agriculture represents a significant challenge for health and safety of our planet. Phytotoxic compounds in OMWW generally prohibit use of untreated OMWWs for agricultural irrigation or direct discharge into surface waters. However, pretreated OMWW can have positive effects on chemical and microbiological soil characteristics, to fight against fungal soil-borne pathogens. Low amounts of OMWW following thermal (TT-OMWW) and high-pressure homogenization (HPH-OMWW) pretreatments counteracted growth of some of 12 soil-borne and/or pathogenic fungi examined. With fungal growth measured as standardized change in time to half maximum colony diameter, Δτ, overall, HPH-OMWW showed increased bioactivity, as increased mean Δτ from 3.0 to 4.8 days. Principal component analysis highlighted two fungal groups: , and , with growth strongly inhibited by the treated OMWWs; and and , with stimulated growth by the treated OMWWs. As a non-thermal treatment, HPH-OMWW generally shows improved positive effects, which potentially arise from preservation of the phenols.
在农业中再利用橄榄油厂废水（OMWWs）对我们星球的健康与安全构成重大挑战。OMWW中的植物毒性化合物通常禁止将未经处理的OMWW用于农业灌溉或直接排放到地表水中。然而，经过预处理的OMWW对土壤的化学和微生物特性可能会产生积极影响，有助于对抗土壤传播的真菌病原体。经过热预处理（TT - OMWW）和高压均质化预处理（HPH - OMWW）后，少量的OMWW能够抑制所检测的12种土壤传播和/或致病真菌中的一些真菌的生长。以达到菌落直径最大值一半所需时间的标准化变化量（Δτ）来衡量真菌生长，总体而言，HPH - OMWW显示出增强的生物活性，平均Δτ从3.0天增加到4.8天。主成分分析突出了两个真菌组：，和，其生长受到处理后的OMWW的强烈抑制；以及和，其生长受到处理后的OMWW的刺激。作为一种非热处理方法，HPH - OMWW通常显示出更好的积极效果，这可能源于酚类物质的保留。
