Abstract
The industry of olive oil extraction in Jordan involves an intensive consumption of water and generates large quantities of olive mill wastewater (OMW). This wastewater has a high pollution risk with biological oxygen demand (BOD). The organic fraction of OMW includes sugars, tannins, polyphenols, polyalcohols, pectins and lipids. The presence of remarkable amounts of aromatic compounds in OMW is responsible for its phytotoxic and antimicrobial effects. The environmental problems and potential hazards caused by OMW had led olive oil producing countries to limit their discharge and to propose and develop new technologies for OMW treatments, such as physicochemical and biological treatments. In the present investigation lebna's whey a local byproduct of widely consumed local yogurt was used with OMW for ethanol production. The obtained results showed that the proteins of lebna's whey can remove substantial amounts of aromatic compounds present in OMW. This was reflected on the reduction of the intensity of black color of OMW and removal of 37% polyphenols. Moreover, the production of ethanol was ascertained in fermentation media composed of whey and in presence of various concentrations of OMW up to 20% OMW. The obtained results showed the possibility to develop a process for improvement and enhancement
