In the post that you quoted, he did not say that oxygen
was produced, yet you said that he was wrong, and now you
are trying to prove yourself right by adding stuff that
was not in the post that you quoted.

No, he was right. The bacteria consume oxygen, thus reducing nitrate to
nitrogen. A lot of other things get reduced of oxygen as well.

No he is wrong. O2 is NOT produced. The oxygen's that are removed from
NO2- end up as H2O. NOT free O2. It is a VERY complex series of events.
Never is O2 produced along the way.

Look into denitrification. It is an ENZYMATIC process in anaerobic bacteria
involving more than one enzyme.

(Look at the part that refers to denitrification and anaerobic bacteria)
