Trophic State Drives the Diversity of Protists in a Tropical River (New River, Belize)
Microorganisms, 2022 Land use disrupts the ecosystem functioning of freshwater systems and significantly affects trophic state. Consequently, biodiversity is severely affected by changes to the ecosystem.

Titrimetric monitoring of a completely autotrophic nitrogen removal process
Water Science and Technology, 2006 Fully autotrophic nitrogen removal processes, such as the combined SHARON-Anammox process, help to improve the sustainability of wastewater treatment. Successful operation of such a completely autotrophic system is, among others, based on the strict control of the SHARON reactor in order to produce an Anammox-suited influent with a 1:1 ammonium:nitrite

Bioresource Technology, 2020 Stabilization of nitrification process and reduction of NO3--N concentration in effluent are the keys to realize mainstream application of partial nitrification-anaerobic ammonia oxidation (PN-anammox) process. The sulfur-based autotrophic denitrification (SADN) process was coupled with the PN-anammox in a single reactor to enhance and stabilize the ...

Heterotrophic denitrification vs. autotrophic anammox – quantifying collateral effects on the oceanic carbon cycle [PDF]
Biogeosciences, 2010 The conversion of fixed nitrogen to N<sub>2</sub> in suboxic waters is estimated to contribute roughly a third to total oceanic losses of fixed nitrogen and is hence understood to be of major importance to global oceanic production and ...

Growth limiting conditions and denitrification govern extent and frequency of volume detachment of biofilms [PDF]
, 2013 This study aims at evaluating the mechanisms of biofilm detachment with regard of the physical properties of the biofilm. Biofilms were developed in Couette–Taylor reactor under controlled hydrodynamic conditions and under different environmental growth ...

Annual plankton community metabolism in estuarine and coastal waters in Perth (Western Australia) [PDF]
PeerJ, 2018 The planktonic metabolic balance that is the balance between gross primary production (GPP) and community respiration (CR) was determined in Matilda Bay (estuarine) and Woodman Point (coastal) in Perth, Western Australia.

Environmental Technology, 2014 Kinetics of sulphur-limestone autotrophic denitrification process in batch assays and the impact of sulphur/limestone ratio on the process performance in long-term operated packed-bed bioreactors were evaluated. The specific nitrate and nitrite reduction rates increased almost linearly with the increasing initial nitrate and nitrite concentrations ...
