Hydrological drought is a process of natural desiccation mainly due to large shortage of rainfall events. Reduced precipitations and prolonged droughts are spreading worldwide and threaten the integrity of aquatic ...
This doctoral thesis studies the abundance, diversity, seasonal dynamics and activity of Epsilonproteobacteria in a meromictic basin of Lake Banyoles during three year cycles. We applied a complementary array of molecular ...
El present treball es centra en l'estudi a diferents nivells dels carotenoides de les espècies marrons de Bacteris Verds del Sofre (GSB, de l'anglès Green Sulfur Bacteria). L'objectiu global ha estat el d'esbrinar quina ...
Autotrophic and heterotrophic microorganisms are two essential functional units in the microbial food web of aquatic ecosystems. They play a key role in nutrient cycling and carbon flow and influence the structure, composition ...
Green bacteria possess one of the most complexes antenna systems within the group of the photosynthetic microorganisms. One reason for this complexity is the high diversity of pigments antenna, the bacteriochlorophylls ...
Pollution by toxic compounds is one of the most relevant environmental damages to ecosystems produced by human activity and, therefore, it must be considered in environmental protection and restoration of contaminated ...
La incidència sobre el suro de defectes sensorials amb descriptors de florit-humitat és un dels principals problemes amb què s'enfronta la indústria surera. Els principals compostos relacionats amb aquest defecte son ...
The Phylum Bathyarchaeota is currently one of the most studied uncultured archaeal phyla. Bathyarchaeota are phylogenetically diverse, globally ubiquitous and especially abundant in marine subsurface sediments. Despite ...
This thesis studied the principal environmental controlling factors and microbial mechanisms involved in leaf litter decomposition in Mediterranean intermittent streams. Additionally, drought disturbance in both Mediterranean ...
This thesis shows how the metals of natural and anthropic origin change significantly the composition of the prokaryotic communities (mainly the composition of bacteria). The β-diversity is the most sensitive variable to ...
La contínua descàrrega de nutrients, sobretot fosfats i nitrogen, és la major causa d'eutrofització dels ecosistemes aquàtics. Els sistemes de tractament basats en aiguamolls construïts s'han emprat per reduir ells nivells ...
Nitrogen pollution in water is common in our environment, especially in places affected by agriculture and livestock, industry or wastewater discharge areas. Ammonium and nitrate are the most common pollutants and can be ...
Se ha estudiado la dinámica del fitoplancton en las lagunas costeras de Aiguamolls de l'Empordà. El fitoplancton esta sujeto principalmente al control "bottom-up", la variabilidad hidrológica y la disponibilidad de nutrientes ...
Biogas is a highly recognized alternative to fossil fuels towards a sustainable energy production. Massive use of biogas depends on the removal of contaminants that may affect performance of processing equipment and energy ...
Denitrifying biocathodes are used to treat nitrogen contaminated water resources. The present PhD dissertation have been characterized different bacterial families with a relevant role in denitrification process. Different ...
