“…In the last decade, the valorisation of OMW has attracted much attention from research teams. It has been shown that an environmental issue could be turned into valuable products 1 such as biofuel, 11 bioactive and nutraceutical compounds, 12 antibacterial and anti-inflammatory compounds, 13 anti-oxidant compounds 14 along with the common polyphenols. 15,16 In the fermentation process of biofuel production, the use of cell immobilisation has many benefits.…”

Physicochemical and microbiological characteristics of a local traditional olive mill wastewater, at Ennakhla-Chlef in northern Algeria, were evaluated. The olive mill wastewater samples had slight acidity of 0.65 % with a pH = 4.88, and electrical conductivity of 34 mS cm −1 . The chemical oxygen demand (COD) and the biological oxygen demand (BOD 5 ) reached up to 183 g l −1 and 7 g l −1 , respectively. In addition, the samples showed 1.72 g l −1 of total phenolic compounds. Preliminary microbiological analysis of the wastewater showed the presence of various microorganisms represented especially by lactic acid bacteria and Enterococcus sp. to the aim of this work was to investigate the possibility of using yeast strains isolated from olive mill wastewater in the fermentation of the latter. The results shown that fermentation with yeast can produce ethanol at an extent of 1.4 % (v/v). This can constitute a strategy for treating mentioned wastewater and transforming it into valuable biomolecules.
