The common method for the disposal of olive oil mill wastewater (OMW) has been its accumulation in evaporation ponds where OMW sediments concentrate. Due to the phytotoxic and antimicrobial effect of OMW, leaks from ponds can pollute soils and water bodies. This work focuses on the search for microorganisms that can be used as inocula for bioremediation of polluted matrices in OMW ponds by means of in situ composting. Two fungi isolated from OMW sediments, Aspergillus ochraceus H2 and Scedosporium apiospermum H16, presented suitable capabilities for this use as a consortium. Composting eliminated the phyto- and ecotoxicity of OMW sediments by depleting their main toxic components. Inoculation with the fungal consortium improved the bioremediation efficacy of the technique by hastening the decrease of phytotoxicity and ecotoxicity and enhancing phytostimulant property of compost produced. This procedure constitutes a promising strategy for bioremediation of OMW polluted sites.
橄榄油厂废水（OMW）的常见处理方法是将其蓄积在蒸发池，在那里 OMW 沉淀物会浓缩。由于 OMW 的植物毒性和抗菌作用，池塘泄漏会污染土壤和水体。这项工作专注于寻找可用于原位堆肥的微生物，以生物修复 OMW 池塘中受污染的基质。从 OMW 沉淀物中分离出的两种真菌，赭曲霉 H2 和枝顶孢霉 H16，作为一个联合体具有合适的用途。堆肥通过耗尽其主要毒性成分，消除了 OMW 沉淀物的植物毒性和生态毒性。接种真菌联合体通过加速降低植物毒性和生态毒性并增强堆肥产生的植物刺激特性，提高了该技术的生物修复效果。该程序为生物修复 OMW 污染场地提供了一种很有前途的策略。
