University of Vigo posted this:Valorization of whey and vinasses by producing antimicrobial extracts using biotechnological processesThis invention is based on the production of antimicrobial extracts with potential application against pathogenic microorganisms. The biotechnological production of antimicrobial metabolites was carried out using Lactobacillus plantarum strains. Two industrial wastes, whey, and wine distilled lees (or vinasses) were assayed in order to make the process economically competitive with regard to the chemical one. The extracts are mainly composed by lactic acid, 3-phenyllactic and bacteriocins. Whey was enzymatically hydrolyzed and the solutions were fermented sequentially or simultaneously. The bioprocesses were carried out continuously or discontinuously
University of Vigo posted this:Procedure for the extraction of biosurfactants contained in corn steep liquorsNowadays, most of the pharmaceutical and cosmetic products in the market contain chemically synthesized surfactants in its composition. In many cases, these surfactants are the same as those used in regular cleanup activities. In order to get more natural and biocompatible products, it would be interesting to include natural surfactants instead of chemical surfactants in the preparation of these pharmaceutical and cosmetic products. These biosurfactants are also present in the formulation of greener nanoparticles, replacing the chemical surfactants currently used in the preparation thereof. Most biosurfactants have antimicrobial activity, which would improve the properties of certain nanoparticles, as well as many pharmaceutical and cosmetic products. The main disadvantage of biosurfactants industrial production is related to the high cost compared to chemically synthesized surfactant production. The solution proposed by the Chemical Engineering research group at the University of Vigo, is the development of eco-friendly simple extraction of biosurfactant from a corn wet-milling industry byproduct, such as corn wash liquors, better known as "corn steep liquor (CSL)", which could compete in terms of cost production with its chemical counterparts.
Fundació URV posted this:Gallic Acid for the treatment of pathologies produced by hyperactivation of renin-angiotensin-aldosterone systemGallic Acid is a naturally occurring phenolic compound that is widely distributed throughout the plant kingdom. Different studies have demonstrated the strong antioxidant, anti-inflammatory, anti-mutagenic and anticancer properties of GA, and daily intake may reduce the risk of diseases and bring health benefits. More recently, Gallic Acid has also been studied for its beneficial effects on cardiovascular diseases. It inhibits dyslipidemia, hepatosteatosis and oxidative stress in high-fat diet fed rats, protects the myocardium against isoproterenol-induced oxidative stress in rats, ameliorates the heart-function defects of myocardial dysfunction associated with streptozotocin-induced type-1 diabetic rats and exhibits anti-hyperglycemic and lipid-lowering properties in high-fat diet mice. Gallic Acid is commonly used as antioxidant by the food industry. However, until now, it is not known that the gallic acid could block the renin-angiotensin-aldosterone system (RAAS), which is the innovative aspect discover for the Nutrigenomic Group for the Gallic Acid. The inhibition of the RAAS by Gallic Acid is considered to be of special relevance because RAAS overactivity is currently associated with not only hypertension but also vascular inflammation, the development of atherosclerosis, left ventricular hypertrophy, nephrosclerosis and cardiovascular events. This discovery has a big importance because it opens a wide field of use for this compound in the food, nutraceutical or pharmaceutical industry.
Fundació URV posted this:ELECTRE-H software package: a tool for data analysis and decision aiding with hierarchical criteriaThe ELECTRE-H Software Package implements two new methods for ranking and ordered classification decision problems considering multiple criteria structured into a hierarchy. The hierarchy of criteria is a tool that allows the decision maker to better organize the problem based on its domain knowledge and needs, decomposing the general problem into smaller sub-problems. Both methods follow the well-known outranking model and belong to the family of ELECTRE methods. The ELECTRE approach is inspired on the voting-like procedure based on the opinion of the majority but also respecting the minorities (by allowing veto power). The software available to use ELECTRE methods does not allow a hierarchical decomposition of the problem, but on a flat organization of criteria. The novelties of these two methods are the following: -It fully applies the standard outranking procedure of ELECTRE at all the levels of the hierarchy of criteria (concordance and discordance indices are obtained from the results of the previous layer and exploited at each node to generate new results). -The user will get a result (a ranking or classification) at each intermediate node of the hierarchy as well as the root (or overall) node. -Preference uncertainty can be managed at each node of the hierarchy with its particular discrimination threshold values. -Veto power can be given to the appropriate nodes in the hierarchy, to avoid compensation with the rest of related criteria. -Different scales of measurement can be used both in the elementary criteria and in the intermediate criteria. -For the case of sorting, simple IF…THEN… decision rules are used to define the categories. The novelty of the software ELECTRE-H is that it is the implementation of these methods given by the authors. This guarantees that the program is fully following the methodology proposed. Its main features are: -Clear and easy-to-understand user interface. -Data can be easily provided using an Excel file. -All the parameters of the model can be easily changed in the user interface. -The results obtained can be graphically displayed (i.e. partial pre-orders, rankings) and exported into a PNG image or text files. Also, the calculations of the results are provided in log files. -Additional statistical tools to compute correlations for different ranking and classification results on the same set of alternatives and hierarchy are available. -A distance-based statistical tool to compare partial preorders is available. -The “Simos revised procedure” to calculate numerical values for criteria weights is available. -Analysis of the results can be done at different levels of the hierarchy. -The software supports large number of alternatives and criteria. Also the structure of the hierarchy is only limited to be a tree (each node has a single parent). The software is designed to be easy to use while providing the full functionality required in these two methods.

UNIVERSIDAD DE ALICANTE posted this:Method for recycling of vessels and other structures composed of fiberglass and resinResearchers at the University of Alicante have developed a method to recycle composite fiberglass structures on a polymer matrix (resin). The process removes the polymer matrix, recovering glass fiber which can be reused. The process is not aggressive with fiberglass. It takes place at room temperature and is able to recover all the fiberglass used. The method is industrially scalable and can be automated. Fiberglass composites and resin are widely used in the construction of boat hulls, tanks, wind turbine blades and many other applications. This method is a very important innovation for the sector and there was no effective method that allowed recovering and reusing these materials.
