摘要

Olive oil mill wastewater(OMW) is produced as waste in oiveoil extraction.With the purpose of treating this highlypolluting waste,a number of experiments were conducted in a laboratory-scale bioreactor with the white rot fungus Phanerochaete flavido-alba.It is known that this fungus is capable of decolorizing OMW in static or semistatic cultures at Erlenmeyer scale and at 30degC.The objective of this work was to prove that P.flavido-alba could decolorize OMW insubmerged cultures and that it is capable of reducing OMW toxicity at room temperature (25degC) and in a laboratory-scale bioreactor.In the experiments conducted,manganese peroxidase (MnP) and laccase enzymes were detected;however,unlike other studies,lignin peroxidase was not found to be present.Decoloration obtained after treatment was 70%.The reduction of aromatic compounds obtained was 51%,and the toxicity of the culture medium was reduced by up to 70%.We can the refore state that P.flavido alba is capable of reducing important environmental parameters of industrial effluents and that porspects arepositive for the use of this process at a larger scale,even when working at room temperature.
