Olive husks, typical solid by-products from the olive oil industry, were selected to carry out anaerobic digestion tests. Before digestion, olive husks were subjected to ultrasonic or thermal pretreatments in order to release the organic matter into solution. Both sonication and thermal pretreatment allowed to solubilize the particulate matter with 22% and 72% increase in soluble organics of ol...

in this study, antifungal property of olive leaf extracts against candida albicans ptcc-5027 was examined. fresh olive leaf extracts were prepared using distilled water in a soxhlet apparatus. the antifungal activity of the extract was analyzed by measuring the minimum inhibitory concentration (mic) and minimum fungicidal concentration (mfc), using the microdilution test and disc diffusion assa...

Olive mill wastewater is an important agro-industrial waste with no established treatment method. The authors have developed a phenol separation method that could potentially cover the cost of waste. purpose this study was to identify any economic hotspots in process, operational and examine margin profit for such process. equipment scaled different capacities then used estimate fixed capital i...

Mushroom polysaccharides are edible polymers that have numerous reported biological functions; the most common effects are attributed to β-glucans. In recent years, it became apparent that the less abundant α-glucans also possess potent effects in various health conditions. Here we explore several Pleurotus species for their total, β and α-glucan content. Pleurotus eryngii was found to have the...

Industrial ecology (IE) promotes the development of industrial systems based on recycling of matter and cascading of energy through cooperation. In this paper, the local/regional industrial ecosystem approach is reflected in two examples from Finland. The local forest industry system is based on renewable resources, waste materials and energy utilisation between forestry companies, a saw-mill, ...

The contamination of soils with dry olive-mill residue can represent a serious problem as being an environmental stressor in plants. It has been demonstrated that inoculation of aqueous extract of olive oil-mill residue (ADOR) with saprobe fungi removes some phenolic compounds. In this paper we studied the effect of ADOR uninoculated or inoculated with saprobe fungi in sunflower seedling roots....

The present study concerns the genotoxicity of olive mill waste water (OMWW) generated in mills producing olive oil in Morocco. The Vicia faba micronucleus test was used to evaluate the genotoxicity of OMWW and the six major phenolic compounds identified by HPLC in this effluent. Five dilutions of OMWW were tested: 0.1, 1, 5, 10 and 20%. Maleic hydrazide was used as a positive control. The resu...

The aim of the current study is to determine impacts leachate recirculation on degradation three compositions municipal solid waste in anaerobic bioreactors. was completed by using six columns with equal volume (0.042m3) containing different densities and waste, order follow over a limited time. Three were studied: simulated fresh standard composition, fermentable actual aged waste. Measurement...
