Development and applications of a high-throughput activity assay, using the ammonia-oxidizing bacteria Nitrosomonas europaea

Creator:

Bartow, Shannon M.

Abstract:

The rising demand on freshwater resources emphasizes the benefit of biogeochemical processes that maintain clean water by removing pollutants such as excess nitrogen. The most sensitive step in the removal of nitrogen from waterways is the oxidation of ammonia, a part of nitrification, which is carried out by ammonia oxidizing...

The effect of silver ions and nanoparticles on biofilms and planktonic cultures of Nitrosomonas europaea

Creator:

Giska, Jonathan R.

Abstract:

Due to the effective antimicrobial properties of silver nanoparticles they represent a significant proportion of all consumer-‐related nanomaterials. The introduction of silver nanoparticles from these products into domestic and industrial wastewater streams poses potential complications for biological treatment systems. A critical component of biological treatment that is extremely sensitive to...
