The bright side of olive mill wastewater: valuables bioproducts after bioremediation

The olive mill wastewater harbors several natural products that are generally wasted in the environment without valorization. The polyphenols are the most predominant compounds found in olive mill wastewater exhibiting toxic effects of the ecosystems when they disposed at high concentrations. Theref...

Description
Summary:The olive mill wastewater harbors several natural products that are generally wasted in the environment without valorization. The polyphenols are the most predominant compounds found in olive mill wastewater exhibiting toxic effects of the ecosystems when they disposed at high concentrations. Therefore, green technology was recently used for the recovery of the valuable wasted compounds and their application in various industrial and medical applications. Hence, the bioremediation using microorganisms proved the potent ability of several strains, especially yeasts to grow on olive mill wastewater and to bioconvert polyphenols into valuable bioproducts. In this review, several types of valorization of olive mill wastewater are discussed. The combination of green technology and bioconversion gives an alternative not only to reduce pollution but also leads to generate high-added bioproducts with an effective economic impact. In addition, some drawbacks that may affect the bioremediation process are also presented.
