The positive effects nitrogen removal capability in a plug-flow microaerobic sludge blanket at low temperature are confirmed by inducing periodic high temperature shocks. This method enables enhancement of metabolic activity and an optimized bacterial community structure of microbes under the conditions of low C/N ratio and temperature. The control reactor was operated at a constant temperature of 20 °C, and the plug-flow microaerobic sludge blanket was subjected to a high temperature shock treatment with three cycles for 94 d. Starting with the initial temperature of 20 °C, after three cycles at temperature (30 °C) shock, the removal efficiencies of ammonium and total nitrogen at the terminal period increased to 68.0% and 54.7% from 51.1% to 35.6%, respectively. The activity and relative abundance of ammonia oxidizing bacteria, nitrite oxidizing bacteria, and anammox bacteria, dominated by Candidatus Brocadia at low temperature, were accordingly enhanced after periodic temperature shocks.

An anaerobic ammonium oxidation-upflow anaerobic sludge blanket (anammox-UASB) reactor was operated without temperature control during the four seasons and was therefore subjected to natural periodic ...
Limited nitrogen removal capacity (mainly nitrate, NO-N) remains a major challenge for subsurface wastewater infiltration system (SWIS). Two nitrogen-removing strains have been isolated from SWIS and ...
Simultaneous nitrogen and phosphorus removal in winter is one of the great challenges in wastewater treatment processes due to the poor bioactivity of microbial communities. In this study, excellent p...

The ability of an organism to reduce susceptibility to heat shock, and adapt to HOT TEMPERATURE.
A family of heat-shock proteins that contain a 70 amino-acid consensus sequence known as the J domain. The J domain of HSP40 heat shock proteins interacts with HSP70 HEAT-SHOCK PROTEINS. HSP40 heat-shock proteins play a role in regulating the ADENOSINE TRIPHOSPHATASES activity of HSP70 heat-shock proteins.
Substances capable of increasing BODY TEMPERATURE and cause FEVER and may be used for FEVER THERAPY. They may be of microbial origin, often POLYSACCHARIDES, and may contaminate distilled water.
A constellation of responses that occur when an organism is exposed to excessive cold. In humans, a fall in skin temperature triggers gasping, hypertension, and hyperventilation.
An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.
