Dephenolization of Olive Mill Wastewater by Pellets of Some White Rot Fungi

Bazı Beyaz Çürükçül Fungus Pelletleri ile Zeytin Kara Suyundan Fenol Giderimi

The present study was aimed at evaluating the phenol removal efficiency of growing cell of some lignin- degrading fungi. The experiments were carried out both at olive mill wastewater (OMWW) based medium and at OMWW medium supplemented with nutrient with Trametes versicolor ATCC200801, Phanerochaete chrysosporium ME 446, and Pleurotus ostreatus. Correlation could be established between phenol removal determined and extracellular enzyme activity measured end of the incubation time; therefore, enzymatic dephenolization experiments were also performed. With experiments related to growing cell, the most stable strain, optimum incubation time, dilution of OMWW, medium were selected as T.versicolor ATCC200801, 9th day, 15%, and only OMWW based medium without nutrient, respectively. In this study, 97% of phenol removal was obtained not including the requirement of adaptation phase, pretreatment, and adding of any nutrients, which these findings, not demonstrated in the previous studies related to OMWW.
