Quick Summary

Nitrosolobus is a genus of bacteria that plays a crucial role in the nitrogen cycle. These microorganisms are nitrifying bacteria, meaning they use inorganic chemicals as an energy source. Specifically, Nitrosolobus bacteria are responsible for converting ammonia in the soil into nitrites. This process is essential for making nitrogen available to plants in a usable form. Along with other genera like Nitrosomonas, Nitrosospira, and Nitrosococcus, Nitrosolobus contributes to the first step of nitrification, which is followed by the conversion of nitrites to nitrates by other bacteria.1
