Department of Biological Sciences, Simon Fraser University, Burnaby, Canada . ABSTRACT Our objective was to determine the role of two invasive bivalves on the concentration of ammonium as well as pH within intertidal surface sediments (0 - 3 and 3 - 6 cm depth) and interstitial waters, within the context of a warming environ...

Souza , Maria Bernadete Amâncio Varesche Affiliation(s) Department of Hydraulics and Sanitation, São Carlos School of Engineering (EESC), University of São Paulo (USP), São Carlos, Brazil . ABSTRACT Anammox bacteria represent a promising alternative for treating ammonium-rich wastewater. In this work reported, biomass performing anaerobic oxidation of ammonium was enriched in a sequencing batch reactor, from sludge used for the treatment of high-nitrogen waste from an amino acid-producing industry. After 89 days of operation, both ammonium and nitrite were consumed. During operation under a...
