Nanotecnología en el sector papelero: mejoras en calidad y permanencia de las fibras de alto rendimiento y secundarias en una economía circular mediante el uso de nanofibras y el refino enzimático
Bio and nano technologies are absent or incipient in papermaking industry and, concretely, in recycling and high-yield pulps sectors. In this sense, the present Thesis uses cellulose nanofibers (CNF), both in bulk and on ...
Technologies to determine quality parameters and the effect of high pressure processing on dry-cured ham
The research for new technologies able to determine quality parameters as well as study the effect of High Pressure Processing (HPP) on dry-cured ham is of scientific interest because the information obtained is useful for ...
Bioremediation of nitrate-polluted groundwater using bioelectrochemical systems
The presence of nitrates (NO3-) in groundwater is a worldwide concern. The high energy demand and environmental impact of available technologies requires investigating new technologies. This thesis was focused on investigating ...
Percepción e imagen de los consumidores españoles del pescado salvaje y del pescado de acuicultura
La tesi doctoral que es presenta a continuació té com a objectiu estudiar la percepció que tenen els consumidors espanyols del peix d’aqüicultura en comparació amb el peix salvatge, des de vàries perspectives: percepció ...
Eliminació d'ions metàl·lics d'aigües residuals d'una indústria de recobriment de superfícies mitjançant residus vegetals
Els ions metàl·lics són contaminants no biodegradables que es poden trobar a les aigües i que poden acumular-se en els organismes vius, causant diverses malalties i trastorns. Un dels metalls més contaminant i àmpliament ...
Productos cárnicos fermentado-curados funcionales y seguros. Nueva vía de ingestión de probióticos
Fermented meats play an important part in many diets and are very appreciate by the consumer. However, these products are an important source of fat and salt, associated to chronic cardiovascular diseases. Therefore, it ...
Integrated operation of membrane bioreactors: simulation and experimental studies
Membrane bioreactors (MBR) are a combination of common bioreactors and membrane filtration units for biomass retention, presenting unique advantages like high effluent quality and a smaller footprint than the one by ...
Effects of operational conditions on the performance of a partial nitritation SBR treating high nitrogen loads
The biological treatment of industrial wastewater containing high nitrogen concentrations (>1000 mg N L-1) and low biodegradable organic matter (bCOD) such as landfill leachate is nowadays challenging. Conventional ...
Les altes pressions i la bioconservació com a estratègies de control de Listeria monocytogenes en productes carnis llestos per al consum. Assajos d’inoculació i modelització matemàtica
The present doctoral dissertation deals with the study of the effect of food preservation technologies, such as high pressure (HP) treatments and biopreservation with nisin, on the behaviour of Listeria monocytogenes during ...
Fat and salt reduction and substitution in small-caliber non-acid fermented sausages
The objective of this thesis is to develop fermented sausages with lower fat and sodium content by means of innovative processing and the use of fat and NaCl substitutes. The effect of sunflower oil and pork lard-based ...
Metal ions removal from polluted waters by sorption onto exhausted coffee waste. Application to metal finishing industries wastewater treatment
A new technology for Cr(VI) and divalent metal ions removal based on metal sorption onto exhausted coffee waste has been developed. Physical and chemical characterization of exhausted coffee waste was explored as well as ...
Rice seeds as biofactories of the production of antimicrobial peptides
A series of antimicrobial peptides (AMPs) derived from the BP134 peptide (a member of the CECMEL11 library) exhibited potent bactericidal effect and low cytotoxicity, and were selected for expression in transgenic rice. ...
Implementació d'eines avançades de control per a l'eliminació de nitrogen i optimització dels costos energètics a l'EDAR de la Vall del Ges
WWTP present two issues: 1) Get adequate depuration performance; 2) Do it with minimal costs. There are many strategies that can be applied to achieve these requirements, but they cannot be applied indiscriminately. In ...
Antimicrobial activity in Bacillus spp. from plant environments against plant pathogens. Relationship with cyclic lipopeptide genes and products
Bacillus subtilis and related species have strong interest in agriculture because several strains are biocontrol agents of plant diseases, which have been recognized as biosafe. In this work, a selective enrichment procedure ...
Valoración de materiales compuestos de HDPE reforzados con fibras de Agave sisalana. Aproximación a un paradigma de geometría fractal para las fibras
Natural fibers have been used recently as reinforcement of polymer-matrix based composites. The present thesis examines the mechanical properties of high density polyethylene (HDPE) composite reinforced with sisal fiber, ...
A multiapproach study of soil attributes under land use and cover change at the Cap de Creus Península, NE Spain
The work presented in this Doctoral Thesis has studied the temporal and spatial patterns of the most relevant soil parameters with special attention posed to soil biological and biochemical dynamics occurring at the studied ...
Evaluación de los efectos no intencionados de los transgenes en plantas modificadas genéticamente (MG) resistentes a plagas y diseñadas como biofactorías de péptidos antimicrobianos
Genetically modified crops are submitted to strict regulation to ensure the safety of consumers and the environment. To complement the comparison between GM plants and their counterparts, in the present Thesis, we evaluated ...
Avaluació del paradigma d'agents en la gestió d'un sistema complex d'aigües residuals
The thesis presents and evaluates the application of the paradigm of agents to the management of the urban wastewater system. The system is conceptualised as a multi-agent system from the development of the models of ...
Desenvolupament d'un protocol per l'aplicació de sistemes basats en el coneixement a la gestió d'estacions depuradores d'aigües residuals urbanes
In this thesis, it is presented a research for the implementation of a supervisory system that integrates different technical to complement and improve the management of Waste Water Treatment Plants. The protocol proposed ...
Estudi del comportament de sistemes biològics de depuració d'aigües residuals mitjançant models mecanístics, optimitzant la informació disponible de les dades obtingudes en línia
The use of simulation as an upgrading tool has been tested on real wastewater treatment plants (WWTP). Currently, the new WWTP have the possibility to monitor some process variables as the flows, oxygen concentrations and, ...
