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 کاملChemical and spectroscopic analysis of olive mill waste water during a biological treatment.
The treatment of olive mill waste water was studied on the laboratory scale. Physico-chemical analyses showed the final products had a mean pH of 5.4 without neutralisation and 5.7 when lime was added to the process. Raising the pH by adding lime had a positive outcome on the degradation of phenols, whose levels were reduced by over 76%. The lime also changed the structure of the organic matter...
متن کاملOlive Mill Waste Extracts: Polyphenols Content, Antioxidant, and Antimicrobial Activities
Natural polyphenols extracts have been usually associated with great bioactive properties. In this work, we investigated in vitro antioxidant and antimicrobial potential of the phenolic olive mill wastewater extracts (OWWE) and the olive cake extracts (OCE). Using the Folin Ciocalteux method, OWWE contained higher total phenol content compared to OCE (8.90 ± 0.728 g/L versus 0.95 ± 0.017 mg/g)....
متن کاملMicronutrient dynamics after thermal pretreatment of olive mill solid waste.
This study investigated metal dynamics, and their bioavailability, before and after thermal pretreatment of olive mill solid waste (OMSW), using a sequential metal extraction scheme. The 11.5% increase of cobalt in the most available fraction after the pretreatment coupled to the increase of methane production rate have been a good indicator that the OMSW anaerobic digestion might be metal limi...
متن کاملProper Treatment and Energy Recovery through Codigestion of Two Phase Olive Mill Waste
Many agrofood industries produce huge amount of waste in a form of biomass as a byproduct. Irregular disposal of this waste can cause a serious harm to the environment. However, such waste has received much attention as a renewable energy source. Recently, protecting the environment through a safe disposal of waste has gained much attention in order to guarantee a sustainable environment and su...
