👉 Rhodobacterium is a type of bacteria commonly found in aquatic environments, particularly in bodies of water like lakes and rivers. It is an essential component of the nitrogen cycle, where it plays a vital role in converting atmospheric nitrogen into bioavailable forms for plants to use. Its importance extends beyond its role in nutrient cycling; Rhodobacterium also serves as a source of energy, carbon dioxide, and other organic compounds, contributing to the production of biogas.
