Nitrate reduction test what does the presence of gas indicate?

Answer if you look up the term Denitrification The formation of gaseous nitrogen and/or oxides of nitrogen from nitrate or nitrite by certain bacteria during ANAEROBIC RESPIRATION. Denitrification only occurs in ANAEROBIC or MICROAEROPHILIC conditions when there is sufficient organic carbon to support reaction. Denitrification may be used as a treatment technology to remove nitrogen oxides from liquid waste streams.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
