Comparison of physiology and genome-wide expression in two Nitrosomonas spp. under batch cultivation
DownloadFall 2014
Ammonia oxidizing bacteria (AOB) play a central role in the nitrogen cycle by oxidizing ammonia to nitrite. Nitrosomonas europaea ATCC 19718 has been the single most studied AOB that has contributed to our understanding of chemolithotrophic ammonia oxidation. As a closely related species,...

The addition of biochar to soil is believed to have positive effects on soil nutrient retention. Enhanced cation exchange capacity, water holding capacity and soil aeration are thought to be some of the benefits provided by biochar. In Alberta, reclamation of disturbed sites may be hastened by...

Exploring nitrifier denitrification in Nitrosomonas communis and Nitrosomonas europaea through physiology and proteomic analysis
DownloadSpring 2023
The current understanding of how ammonia oxidizing bacteria (AOB) produce the potent greenhouse gas nitrous oxide is incomplete and inaccurate since most studies are focused on the model organism for the group, Nitrosomonas europaea, which does not represent the physiological diversity of AOB....

Understanding the ecology of microorganisms is essential for optimizing aquaponics systems. Effects of pH and inoculum on ammonium removal and dynamics of microbial community composition from all compartments of lab-scale aquaponics systems were examined. Initial ammonium accumulation in systems...
