The bacteria responsible for oxidizing NO₂⁻ (nitrite) and NO₃⁻ (nitrate) in soils are Nitrobacter species. They play a crucial role in the nitrification process, which converts nitrites into nitrates, a more stable form of nitrogen that plants can use for growth. The bacterium Nitrobacter somonas is a key player in this process.
