Conference lecture
Open AccessBiomass 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
Rodríguez Abalde, Ángela; Guivernau Ribalta, Miriam; Prenafeta Boldú, Francesc Xavier; Flotats Ripoll, Xavier; Fernández García, Belén (2019-04-06)
Article
Open AccessMicrobial 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
Calderer, M.; Martí Gregorio, Vicenç; De Pablo, Joan; Guivernau Ribalta, Miriam; Prenafeta Boldú, Francesc Xavier; Viñas Canals, Marc (2014-03-01)
Article
Restricted access - publisher's policyEnhanced 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
Pelissari, Catiane; Guivernau Ribalta, Miriam; Viñas, Marc; García Serrano, Joan (2018-09)
Article
Restricted access - publisher's policyNitrogen 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
Sotres Fernandez, Ana; Cerrillo Moreno, Míriam; Guivernau Ribalta, Miriam; Prenafeta Boldú, Francesc Xavier; Magrí Aloy, Albert; Illa Alibés, Josep; Bonmatí Blasi, August; Viñas Canals, Marc (2012)
Conference lecture
Restricted access - author's decisionIn 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
Magrí Aloy, Albert; Guivernau Ribalta, Miriam; Delavari, Azar; Flotats Ripoll, Xavier; Viñas Canals, Marc; Prenafeta Boldú, Francesc Xavier; Vanotti, M.B. (2013)
Conference report
Open AccessAnaerobic 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?.
Ruiz Sánchez, Josep; Fernández García, Belén; Viñas Canals, Marc; Guivernau Ribalta, Miriam; Tey, Laura; Riau Arenas, Victor; Flotats Ripoll, Xavier; Prenafeta Boldú, Francesc Xavier (2016)
Conference lecture
Open AccessBiomass 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
Ruiz Sánchez, Josep; Fernández García, Belén; Viñas Canals, Marc; Guivernau Ribalta, Miriam; Tey, Laura; Riau Arenas, Victor; Flotats Ripoll, Xavier; Prenafeta Boldú, Francesc Xavier (Internatinal Water Association (IWA), 2016)
Conference lecture
Restricted access - publisher's policyAmmonia 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 ... -
