Question

what type of bacteria use the enzyme nitrate reductase to metabolize nitrogen oxides and transform them back to nitrogen gas?

Answer 1

Denitrifying Bacteria such as Pseudomonas aeruginosa is the type of bacteria that use enzyme nitrate reductase to metabolise nitrogen oxides to nitrogen gas.

Denitrification is the process whereby nitrites or nitrogen oxides is converted to nitrogen gas by a denitrifying Bacteria such as Pseudomonas.

Pseudomonas aeruginosa uses enzyme nitrate reductase to reduce nitrate to nitrite.

Then nitrite is then converted back to nitrogen gas.

Therefore, Pseudomonas aeruginosa is a type of bacteria that uses enzyme nitrate reductase.
