This study was done in order to reduce the negative effectsphenolic compounds included in the olive mill wastewater added to the cultivatedsoil and to study the individual and collective ability of fungal and bacterial isolatesto dismantle them. The experiment, conducted in 2020 with randomization inexperimental design, consisted of six treatments and three replications. First fourtreatments had olive mill wastewater treated with fungal isolates Penicillium sp,Aspergillus flavos and bacterial isolates Pseudomonas sp,Bacillus sp individually.The fifth treatment included collective use of both isolates, in addition to the controlwhich was without any treatment. The results of the statistical analysis showed thatthe phenolic compounds amount remained in the treated water which indicated thesuperiority of Penicillium sp over all treatments, where the apparent superiority ofphenolic compounds dismantling was over bacterial isolates. However it wassignificantly over the collective effects of fungal and bacterial isolates, Aspergillusflavos and the control..
