Molts bacteris del grup fluorescent del gènere Pseudomonas són capaços de controlar malalties de les plantes causades per fongs i bacteris fitopatògens (ACBs) o mostren activitat com a bacteris promotors del creixement de ...
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 ...
En la primera part del present treball es presenta la investigació duta a terme sobre la reacció d'hidroesterificació d'olefines. S'analitzen els factors que afecten la reactivitat i quimioselectivitat de les reaccions ...
La creciente preocupación y concienciación de la sociedad respecto el medio ambiente, y en consecuencia la legislación y regulaciones generadas inducen a la modificación de los procesos productivos existentes en la industria ...
The aim of this doctoral thesis was to evaluate the application of microbial transglutaminase (MTGase), produced by BDF Natural Ingredients, in the manufacture of acid and enzymatic coagulation fresh cheeses. In the case ...
Computed Tomography and Microcomputed Tomography are X-ray based technologies. They were tested in this thesis as potential tools for the optimization of the processing of dry-cured meat products. On one hand, several ...
La adsorció sobre carbó actiu és un tractament habitual para a l'eliminació de metalls contaminants d'afluents aquosos. Amb la finalitat de reduir el cost dels tractament actuals s'està estudiant la utilització d'adsorbents ...
En este trabajo se ha estudiado el potencial tanto los filamentos de cáñamo como de la cañamiza como refuerzo/carga del polipropileno. La modificación de estos materiales se realiza para lograr una mayor compatibilidad con ...
En una tesi anterior (Puig, 2004) es varen estudiar els aspectes mecànics vinculats al desfibratge i als consums energètics associats al procés de desintegració per acabar quantificant les forces implicades en el procés ...
The combination of two membrane technologies coupled together in series has become a standard technology when it comes to producing reclaimed water of high quality for potable reclamation or industrial applications. This ...
Human population has had an impact on the natural phosphorus’ cycle, a limited resource, and the predictions show that this resource could be exhausted in 100-250 years. Therefore, the actions for the coming 10-25 years ...
En aquest estudi, la toxicitat de diversos metalls pesants i l'arsènic va ser analitzada utilitzant diferents models biològics.<br/>En la primera part d'aquest treball, el bioassaig de toxicitat Microtox, el qual està basat ...
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 ...
La desintegració és una etapa important en la recuperació de paper vell, ja que té importants conseqüències en consum d'energia i en el comportament de les etapes posteriors.<br/>Per això els objectius es centren en analitzar ...
Summary Nowadays, ammonium (NH4+) is a pollutant present in all kinds of water bodies, leading to multiple environmental and health issues. The current NH4+-removing technologies are very expensive, as they require a lot ...
In 2015 the average concentration of CO2 in the atmosphere exceeded 400 ppm. Some technologies, including CO2 capture and storage, are palliative. However, the development of alternatives to burning of fossil fuels focuses ...
The fruit production is threatened by several bacterial diseases, such as fire blight of apple and pear, bacterial canker of kiwifruit, bacterial spot of stone fruits, and angular leaf spot of strawberry. The conventional ...
Biological nutrient removal has been studied and applied for decades in order to remove nitrogen and phosphorus from wastewater. However, more anthropogenic uses and the continued demand for water have forced the facilities ...
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 ...
Macroalgae have been recognized as an interesting source of compounds with multiple applications in different fields due to their various bioactivities since current trends are moving towards the use of alternative compounds ...
