Time response of Nitrobacter to toxicity

open access: yesEnvironment International, 1984
Abstract Nitrobacter toxicity experiments were conducted by using a mixed culture obtained from biomass on rotary biological contactors. The culture was treated with inorganic and organic toxicants, and the toxic effect was expressed in nitrite consumption. Contact time was found to be an important factor in toxic effect.

Soil Environmental Factors Dominate over Nitrifier and Denitrifier Abundances in Regulating Nitrous Oxide Emissions Following Nutrient Additions in Alpine Grassland

open access: yesAgronomy
Nutrient additions including nitrogen (N) and phosphorus (P) are widely considered as an important strategy for enhancing grassland productivity. However, the effects of these nutrients additions on soil nitrous oxide (N2O) emissions and the underlying ...
