Coexistence of nitrifying, anammox and denitrifying bacteria in a sequencing batch reactor
Elevated nitrogen removal efficiencies from ammonium-rich wastewaters have been demonstrated by several applications, that combine nitritation and anammox processes. Denitrification will occur simultaneously when organic carbon is also present.

ABSTRACT Livestock farming and its slurry management represent a significant contributor to global anthropogenic ammonia (NH3) and greenhouse gas (GHG) emissions, resulting in negative impacts on the environment. The aim of this study was to evaluate the effect of two microbial slurry additives (A1, A2) on the emissions of NH3, methane (CH4) and carbon

Microbial oxidation of arsenite in a subarctic environment: diversity of arsenite oxidase genes and identification of a psychrotolerant arsenite oxidiser [PDF]
Background: Arsenic is toxic to most living cells. The two soluble inorganic forms of arsenic are arsenite (+3) and arsenate (+5), with arsenite the more toxic. Prokaryotic metabolism of arsenic has been reported in both thermal and moderate environments

Toxic Response of Nitrobacter to Orange II and Direct Blue 71
Tolerance of Nitrobacter to Orange II (C.L. 15510) and Direct Blue 71 (C.I. 34140) dyes was determined by total viable count. There was decrease in percentage log survival with increase in concentration of the toxicants and increase in exposure time ...
