Influence of pH on the culture of Scenedesmus obliquus in olive-mill wastewater

Olive-mill wastewater (OMW), an agro-industrial by-product from olive-oil milling (with the three-phase extraction method), was used experimentally as 5% (v/v) of the medium to culture Scenedesmus obliquus CCAP 276/3A. The characterization of the wastewater indicated a nitrogen deficiency. The highest specific growth rate of S. obliquus μm = 0.022 h−1 was found when the medium was maintained at a constant pH value of 7.0. The biomass...
