Obtaining value-added products from agricultural waste is one of the most relevant key objectives to develop a greener bio-based economy and a future sustainable agricultural framework. This is indeed the objective of LIGNOFOOD project: ingredients for food and beverage industry from a lignocellulosic source. LIGNOFOOD project brings together 5 recognized research organisms and 4 bio-technological SMEs to deal with obtaining xylooligosaccharides (XOS) with the greatest prebiotic potential and xylitol from industrial hemp, an ecological resource of lignocellulosic material. Industrial hemp is one of the oldest cultivated plants and responsible of numerous environmental benefits; resistant to pests allowing reduction of agricultural biocides use, positive crop-sequencing effect for other bioenergy crops, and fast crop growth with low husbandry costs. Thus, it is a renewable resource with great potential to obtain ingredients of added value. XOS are non-digestible dietary components that have been recently reported to stimulate growth and/or modify the metabolic activity of beneficial bacteria and improve gut health. On the other hand, xylitol is also of great value because of its low caloric and low glycemic index, and used as sugar substitute. The combination of two production biotechnologies in one integrated process to obtain two products (XOS and xylitol) from a renewable resource is of great interest in terms of cost efficiency and sustainability. Furthermore, the health functionality and safety of the ingredients will be assured, and their addition to food matrices for food product development will be explored according to the sensorial properties and consumer acceptance evaluation to meet the final user/stakeholder preferences and needs. The participating SMEs will be able to exploit the results of these studies for XOS and xylitol commercialization and improve their competitiveness by gaining access to the rapidly growing market of functional foods.

The project represents a technical and technological contribution to purification of polluted drinking waters by selective biodegradable sorbent derived from biowastes. ChitoClean will implement a holistic approach taking into account all necessary steps of a novel drinking water treatment process. This approach is centred on chitin-based biosorbents, which are already used in different applications and known for their excellent adsorption capacities. Natural materials made from carcasses of shrimps and crabs are to be physically and chemically enhanced to be suitable for the use in drinking water purification applications. The characteristics that the Enhanced Chitin-based Materials (ECM) will ideally present are improved stability, adaptability to different forms of filters and maximal adsorption rates and capacities. ECMs are to be implemented in prototypes of filtering units. Different kinds of prototypes will be generated in order for the new technology to be applicable for different use: household filters, on-site water treatment in wells, big-scale treatment and integration into central water supply systems of small towns. In parallel products and processes will be tested in order to regenerate charged filters and extend their lifetime of the latter. As despite material regeneration - ECM will eventually lose its absorption capacity and be spent needing replacement, the project also investigates on methods to recycle and/or dispose of the old filter material. In addition, the health aspect will be taken into account by evaluating the effect of the treatment by ECM on the mineral content/balance of the purified water. First discussions towards validation of results by potential customers are supposed to take place within the External Advisory Board regrouping representatives of stakeholder groups e.g. industry and water suppliers. Exploitation of results and IPR management are substantial components of the project and will be streamlined through the projects Exploitation & Dissemination Strategy. In order to raise awareness for project results, a major stakeholder event is planned at the end of the project.

In this paper, a simple and sensitive method for the electrochemical determination of phenol in soil sample using disposable screen-printed glassy carbon (GC) electrode surface modified with an electrografted aminophenol film, via the electrochemical reduction of its prepared aminophenol diazonium salt in non-aqueous media, is presented. 1 mM of aminophenol diazonium salt (APDAS) in 100 mM tetrabutylammonium tetrafluoroborate (TBATFB) was used for modification of GC electrode surface in this study. The surface modification of GC electrode was performed with aminophenol (AP) using cyclic voltammetry (CV), whereas the characterization of this sensor electrode was performed using CV and electrochemical impedance spectroscopy. The modification process was carried out in non-aqueous media, whereas phenol determination was carried out in aqueous media. Acetonitrile (MeCN) for providing non-aqueous condition and Britton-Robinson (BR) buffer solution at pH 10 and 100 mM KCl solution for providing aqueous condition were used. As the final of this study, a reaction mechanism was suggested for the binding of phenol to aminophenol modified GC electrode surface. 0.1316 mgL -1 phenol was determined in soil sample by using AP modified GC electrode. © Sila Science.

A novel 'turn-on' fluorescent probe with perylene tetracarboxylic bisimide (PBI) as the fluorophore and di(2-(salicylideneamino))ethylamine (DSEA) as the metal ion receptor was designed. The capability of the prepared probe to detect metal ions was evaluated by the changes in its emission intensity. The probe demonstrated a considerable emission enhancement (ca. 110-fold) in the presence of Al3+in MeCN with high selectivity and sensitivity. Furthermore, the considerably 'off-on' fluorescence response concomitantly led to the apparent color change from colorless to brilliant yellow, which could also be identified by naked eye easily under UV lamp. © 2014 Elsevier Ltd.

In this study, sporopollenin of Lycopodium clavatum spores was used for the sorption experiment. Glutaraldehyde (GA) immobilized sporopollenin (Sp), is employed as a sorbent in sorption of selected heavy metal ions. The sorbent prepared by sequential treatment of sporopollenin by silanazing compound and glutaraldehyde is suggested for sorption of Cu(II), Zn(II) and Co(II) from aqueous solutions. Experimental conditions for effective sorption of heavy metal ions were optimized with respect to different experimental parameters using batch method in detail. Optimum pH range of Cu(II) has occurred at pH≥5.5 and Zn(II), Co(II) at pH≥5.0, for the batch method. All of the metal ions can be desorbed with 10cm3 of 0.5moldm-3 of ethylenediaminetetraacetic acid (EDTA) solution. Langmuir, Freundlich and Dubinin-Radushkevich (D-R) isotherm equations were applied to the experimental data. Thermodynamic parameters such as free energy (ΔGo), entropy (ΔSo) and enthalpy (ΔHo) were also calculated from the sorption results used to explain the mechanism of the sorption. The results indicated that this sorbent is successfully employed in the separation of trace Cu(II), Zn(II) and Co(II) from the aqueous solutions. © 2010 Elsevier B.V.

A method was developed for viable and rapid determination of seven polychlorinated biphenyls (PCBs) in water samples with vortex-assisted liquid-liquid microextraction (VALLME) using gas chromatography-mass spectrometry (GC-MS). At first, the most suitable extraction solvent and extraction solvent volume were determined. Later, the parameters affecting the extraction efficiency such as vortex extraction time, rotational speed of the vortex, and ionic strength of the sample were optimized by using a 23 factorial experimental design. The optimized extraction conditions for 5 mL water sample were as follows: extractant solvent 200 μL of chloroform; vortex extraction time of 2 min at 3000 rpm; centrifugation 5 min at 4000 rpm, and no ionic strength. Under the optimum condition, limits of detection (LOD) ranged from 0.36 to 0.73 ng/L. Mean recoveries of PCBs from fortified water samples are 96% for three different fortification levels and RSDs of the recoveries are below 5%. The developed procedure was successfully applied to the determination of PCBs in real water and wastewater samples such as tap, well, surface, bottled waters, and municipal, treated municipal, and industrial wastewaters. The performance of the proposed method was compared with traditional liquid-liquid extraction (LLE) of real water samples and the results show that efficiency of proposed method is comparable to the LLE. However, the proposed method offers several advantages, i.e. reducing sample requirement for measurement of target compounds, less solvent consumption, and reducing the costs associated with solvent purchase and waste disposal. It is also viable, rapid, and easy to use for the analyses of PCBs in water samples by using GC-MS. Copyright © 2011 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

Renewable energy is clean sources and has a much lower environmental impact than other energy sources. In Turkey, solar energy investments have been developed rapidly in recent years. Site selection for solar farms is a critical issue for large investments because of quality of terrain, local weathering factors, proximity to high transmission capacity lines, agricultural facilities and environmental conservation issues. Multi criteria evaluation methods are often used for different site selection studies. The purpose of this study was to determine suitable site selection for solar farms by using GIS and AHP in the study area. The final index model was grouped into four categories as "low suitable", "moderate", "suitable" and "best suitable" with an equal interval classification method. As a result, 15.38% (928.18 km2) of the study area has low suitable, 14.38% (867.83 km2) has moderate suitable, 15.98% (964.39 km2) has suitable and 13.92% (840.07 km2) has best suitable for solar farms area. 40.34% (2434.52 km2) of the study area is not suitable for solar farm areas. © 2013 Elsevier Ltd.

An experimental investigation was conducted to evaluate the effects of polypropylene fiber inclusions on the geotechnical characteristics of a clayey soil that was chemically stabilized with cement and fly ash. For all stabilized soils, cement and fly ash were added at 8% and 30%, respectively. Reinforced stabilized soil specimens were prepared at four different percentages of fiber content (0.25%, 0.50%, 0.75%, 1.0%) and three different fiber lengths (6 mm, 12 mm, 20 mm). Unconfined compressive and split tensile strength tests were carried out after 7-and 28-day curing periods. The volume change characteristics of the reinforced stabilized soil were determined using shrinkage limit and crack reduction values. The interactions between the fiber surface and the stabilized soil were analyzed by means of scanning electron microscopy. According to the results, the compressive and especially the tensile strength values increased to a great extent following the addition of fiber into the stabilized soil. The highest strength values were obtained with 0.5-0.75% content for the 12 mm-long fibers. The shrinkage limit and crack reduction values increased with increased fiber content and greater fiber length, whereas volume changes decreased. © 2013 Thomas Telford Ltd.

The purpose of this study is to produce a groundwater spring potential map of the Sultan Mountains in central Turkey, based on a logistic regression method within a Geographic Information System (GIS) environment. Using field surveys, the locations of the springs (440 springs) were determined in the study area. In this study, 17 spring-related factors were used in the analysis: geology, relative permeability, land use/land cover, precipitation, elevation, slope, aspect, total curvature, plan curvature, profile curvature, wetness index, stream power index, sediment transport capacity index, distance to drainage, distance to fault, drainage density, and fault density map. The coefficients of the predictor variables were estimated using binary logistic regression analysis and were used to calculate the groundwater spring potential for the entire study area. The accuracy of the final spring potential map was evaluated based on the observed springs. The accuracy of the model was evaluated by calculating the relative operating characteristics. The area value of the relative operating characteristic curve model was found to be 0.82. These results indicate that the model is a good estimator of the spring potential in the study area. The spring potential map shows that the areas of very low, low, moderate and high groundwater spring potential classes are 105.586km 2 (28.99%), 74.271km 2 (19.906%), 101.203km 2 (27.14%), and 90.05km 2 (24.671%), respectively. The interpretations of the potential map showed that stream power index, relative permeability of lithologies, geology, elevation, aspect, wetness index, plan curvature, and drainage density play major roles in spring occurrence and distribution in the Sultan Mountains. The logistic regression approach has not yet been used to delineate groundwater potential zones. In this study, the logistic regression method was used to locate potential zones for groundwater springs in the Sultan Mountains. The evolved model was found to be in strong agreement with the available groundwater spring test data. Hence, this method can be used routinely in groundwater exploration under favourable conditions. © 2011 Elsevier B.V.
