Characterization of methanogenic biomass from a full-scale digester that might harbour SAO activity
(2015)
Comunicación de congreso
Acceso abiertoBiomass from a full-scale anaerobic digester treating nitrogen-rich wastes was characterized by methanogenic batch activity assays at different ammonia concentrations. SAO was demonstrated by isotopic 13C fractionation of ... -
Characterization of microbial community dynamics during the anaerobic co-digestion of thermally pre-treated slaughterhouse wastes with glycerin addition
(2019-04-06)
Artículo
Acceso abiertoMicrobial community dynamics during the anaerobic co-digestion of pig manure, pasteurized slaughterhouse waste and glycerin were studied in a lab-scale CSTR. The feed composition was optimized through progressive co-substrate ... -
Effects of enhanced denitrification on hydrodynamics and microbial community structure in a soil column system
(2014-03-01)
Artículo
Acceso restringido por política de la editorialEnhanced heterotrophic denitrification by adding glucose was investigated by means of a soil column experiment which simulated the groundwater flow. The carbon-to-nitrogen ratio was the main factor determining denitrification ... -
Effects of partially saturated conditions on the metabolically active microbiome and on nitrogen removal in vertical subsurface flow constructed wetlands
(2018-09)
Artículo
Acceso restringido por política de la editorialNitrogen dynamics and its association to metabolically active microbial populations were assessed in two vertical subsurface vertical flow (VF) wetlands treating urban wastewater. These VF wetlands were operated in parallel ... -
Electroactive biofilm adapted to a high nitrogen loads and electricity generation in a microbial fuel cell fed with pig slurries
(2012)
Comunicación de congreso
Acceso restringido por decisión del autorIn the present study, the anodic biofilm of two MFC reactors (MFC-1 and MFC-2) working at high ammonium loading rates were characterized in electrochemical and microbial terms. -
Feasibility of enriching anammox bacteria using sludge from two wastewater treatment plants
(2013)
Texto en actas de congreso
Acceso abiertoAnaerobic ammonium oxidation (anammox) is a promising biotechnology suitable for the removal of nitrogen from wastewaters. A proper choice of the seeding sludge and operational conditions is critical when dealing with the ... -
How much of microbial genetic expression profile, depending on ammonia stress, the anaerobic digesters change?.
(2016)
Comunicación de congreso
Acceso abiertoBiomass from two full-scale anaerobic digester treating different wastes regarding to nitrogen concentrations and operating under different hydraulic retention time was characterized by methanogenic batch activity assays ... -
Influence of support materials on methanogenic biofilm formation in ammonia rich environments
(Internatinal Water Association (IWA), 2016)
Comunicación de congreso
Acceso restringido por política de la editorialAmmonia is the main inhibitor of methanogenesis during the anaerobic digestion (AD) of protein-rich materials. Promoting biomass development as biofilm is a well-known strategy to overcome inhibition by toxic compounds in ... -
Microbial community dynamics in two-chambered microbial fuel cells : effect of different ion exchange membranes
(2015-08-01)
Artículo
Acceso abiertoBACKGROUND: The utilization of different kinds of ion exchange membrane is a common practice in bioelectrochemical systems such as two-chambered microbial fuel cells (MFCs). However, little is known about the effect of ... -
Occurrence of perchlorate in groundwater samples from Catalonia
(2009)
Comunicación de congreso
Acceso restringido por decisión del autorThe perchlorate ion competitively blocks iodine from entering the thyroid gland, which may lead to a decrease in production of thyroid hormones (T3 and T4) that are essential for neurodevelopment (Wolff, J., 1998). ... -
Operational, design and microbial aspects related to power production with microbial fuel cells implemented in constructed wetlands
(2015-11-01)
Artículo
Acceso abiertoThis work aimed at determining the amount of energy that can be harvested by implementing microbial fuel cells (MFC) in horizontal subsurface constructed wetlands (HSSF CWs) during the treatment of real domestic wastewater. ... -
Unraveling the active microbial populations involved in nitrogen utilization in a vertical subsurface flow constructed wetland treating urban wastewater
(2017-04)
Artículo
Acceso abiertoThe dynamics of the active microbial populations involved in nitrogen transformation in a vertical subsurface flow constructed wetland (VF) treating urban wastewater was assessed. The wetland (1.5 m2) operated under average ...
