Denitrators

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.

SEE: http://www.reefscapes.net/articles/a...ogencycle.html

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

In the post that you quoted, he did not say that oxygen
was produced

Neither did I. When did I write O2 was produced? Read this again: NO3
goes to N2 and H2O. No O2 is produced in this process (denitrification).

, 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.

I am supporting my argument that I had from the very beginning by providing
a web site link as support.

Wayne reread my posts.

I said from the VERY beginning that NO3 goes to H2O and N2. Never did I
write O2 was produced.

You wrote I was wrong from the beginning.

Who do you think is right now Wayne?

You must feel pretty silly?

Hehehehe. Lol lol lol.

lol

LOL you keep turning your statements around, and when you
quote me, you deliberately leave off important parts of
the previous post in your quote to cover your tracks.

Wayne what statements of MINE have I turned around?

Give one.

Patterson wrote this very early on:"I don't know how they work, but the goal
is to turn the nitrates (NO3) into
gaseous nitrogen and oxygen."

Gaseous nitrogen and oxygen to 'me' mean O2 and N2. Do you STILL think he
is right?

I will write it again so there is no confusion:
2NO3- + 12H+ --- 6H2O and N2

If you are confused where the H+ come from let me know.

Isn't it that the gaseous nitrogen is released as
not usable byproduct but the oxygen is fixed in the respiration
process and goes through the bacteria body later released
as water ?
Bacteria needs oxygen, but oxygen is not available in gaseous
form, so it uses it as a part of nitrates ion and is able to
tear apart the nitrates ion to grab oxygen for itself and
release not-needed nitrogen.

I think similar process is when there is a cyanobacteria
in a nitrates poor environment - they can get nitrogen
needed in biological processes to fix amino-acids from
gaseous form and other bacteria and plant need nitrates
or ammonia since they are unable to fix nitrogen from air.
