Antimicrobial Activity of Olive Mill Waters (Alpechin) and Biotransformed Mill Wastewater Waste- Olive Oil
Olive oil extraction produces a great volume of residue. These olive mill wastes are known as alpechin. This wastewater is a powerful pollutant, resistant to degradation and presents a severe environmental problem related to its high organic content made up largely of simple phenolic compounds, that have been described as being both antimicrobial and phytotoxic. This paper reviews briefly the a...
متن کاملDilution of olive mill wastewater eliminates its phytotoxicity and enhances plant growth and soil fertility Munir
Olive Mill Wastewater (OMW) is phytotoxic and all attempts to treat it are expensive and therefore alternative less expensive techniques should be developed to reduce its phytotoxicity. The objective of this study is to determine whether the dilution of OMW with water improves its suitability for soil application and enhances plant growth without polluting the environment. The following treatme...
متن کاملShort-term impact of dry olive mill residue addition to soil on the resident microbiota.
The short-term response of the resident soil bacterial and fungal communities to the addition of 5% (w/w) of either dry olive mill residue (DOR), DOR treated with Phlebia sp. (PTDOR) or DOR previously extracted with water (WEDOR) was investigated. As opposed to bacteria, the diversity of fungi increased upon the amendments as assessed by denaturing gradient gel electrophoresis of 18S rDNA. Over...
متن کاملPhotochemical UV/TiO2 treatment of olive mill wastewater (OMW).
Olive mill wastewater (OMW) was treated by photocatalysis using TiO2 under UV irradiation on the laboratory scale. The chemical oxygen demand, the coloration at 330nm, and the level of phenols all showed decreases which, after a 24-h treatment, reached 22%, 57% and 94%, respectively. The differences between these three values indicate the persistence of colourless, non-phenolic compounds. Appli...
متن کاملBiological treatment of olive mill wastewater by non-conventional yeasts.
The ability of lipolytic yeasts to grow on olive mill wastewater (OMW)-based medium and to produce high-value compounds while degrading this waste, was tested. OMW collected from three-phase olive mills from the North region of Portugal were characterized and used. OMW with COD ranging from 100 g L(-1) to 200 g L(-1) were supplemented with yeast extract and ammonium chloride. Studies of OMW con...
