BACKGROUND: The aim of this work was to study the ability of two different wild type strains of the yeast Yarrowia lipolytica to grow on olive mill wastewater (OMW) and their potential to produce high-value products such as lipases. Factors that affect cellular growth and OMW degradation were studied, such as nitrogen supplementation, cells concentration and surfactant addition. RESULTS: Both s...

This paper presents a novel skill-assist (or power-assist) method which employs neuro-fuzzy systems in an Omni-directional Wheelchair (OMW). This function allows the attendants of elderly or handicapped people to deal with heavy loads while the operability problem of moving the OMW laterally or rotating it around the OMW’s Center of Gravity (CG) is also solved. A fuzzy reasoning method is propo...

Abstract: In this paper, a power assist system of Omni-directional Mobile Wheelchair(OMW) for attendants aiming at the reduction of incidence by operation of attendants is presented. The OMW presented in this paper, has 3 degrees of freedom, so it is important to consider operationality. The control system must be developed considering both operationality and comfort. A Power assist controller ...

seasonal accumulation and incorrect disposal of olive mill by-products may be detrimental to the environment. conversely, their proper recycling as soil amendments may be a sustainable solution. therefore, the objectives of this three-year field trial were: (i) investigating the effects of olive mill wastewater (omw) and pomace compost (pc) on plant nutritional status and yield in an organic ol...

Problem statement: Olive Mill Wastewater (OMW) is an ambivalent by-product of the olive oil production, which appears in huge amounts every year after the olive-harvest in the production countries, mainly in the Mediterranean region. OMW is characterized by a high organic load and i.a. contains considerable amounts of phytotoxical polyphenols, which cause important environmental problems. Appro...

Swine wastewater (SW) and olive mill wastewater (OMW) are two problematic wastes that have become major causes of health and environmental concerns. The main objective of the current work was to evaluate the efficiency of the co-digestion strategy for treatment of SW and OMW mixtures. Mesophilic batch reactors fed with mixtures of SW and OMW showed that the two adapted sludges Gadot and Prigat ...

Photocatalytic technique had already been employed in the treatment of olive mill wastewater (OMW) using the photocatalysis in suspension. The coupling of photocatalytic and membrane techniques should result in a very powerful process bringing great innovation to OMW depollution. Despite the potential advantages using these hybrid photoreactors, research on the combined use of photocatalysis an...

Olive processing wastewaters (OPW), namely olive mill wastewater (OMW) and table-olive wastewaters (TOW) were evaluated for their antibacterial activity against five Gram-positive and two Gram-negative bacteria using the standard disc diffusion and thin layer chromatography (TLC)-bioautography assays. Disc diffusion screening and bioautography of OMW were compared to the phenolic extracts of ta...

Olive mill wastewater (OMW) constitutes a major cause of environmental pollution in olive-oil producing regions. Sixty wood-rot macrofungi assigned in 43 species were evaluated for their efficacy to colonize solidified OMW media at initially established optimal growth temperatures. Subsequently eight strains of the following species were qualified: Abortiporus biennis, Ganoderma carnosum, Hapal...

The valorization of food processing by-products, wastes and effluents is a challenging opportunity for the sustainable and competitive development of several relevant industrial sectors. One of the best examples of a biorefinery applied to plant processing wastes is that of the olive oil sector by-products including leaves and olive mill wastewaters (OMW). Management of OMW, in particular, has ...
