No. Only a nuclear reaction can change oxygen into nitrogen, and bacteria are not capable of such reactions.
Although the air is made up of about 80% nitrogen, plants cannot use nitrogen in this N2 form. Nitrogen fixing bacteria change nitrogen into the form of soluble nitrates so that plants can use it. Other bacteria, known as de-nitrifying bacteria, change nitrates back into N2, which completes the nitrogen cycle

nitrogen
Nitrogen gas (N2) is converted by nitrogen-fixing bacteria that live in the root nodules of Legumes into NH3.

When oxygen is present, nitrogen in the ground is typically found in the form of nitrate (NO3-). This is because nitrogen undergoes nitrification, a process where certain bacteria convert ammonium into nitrate in the presence of oxygen. Nitrate is a common form of nitrogen that plants can readily absorb.
