👉 Nitrosococcus is a type of bacteria that has been associated with nitrogen fixation in soil. It primarily lives on organic matter and resists the effects of anaerobic conditions, making it suitable for use as an agricultural resource. Nitrosococcus can be found in various environments such as forests, grasslands, and wetland areas, where it can thrive due to its high ability to fix nitrogen from the atmosphere into a form that can be used by plants.
