Question
The transformation of nitrates to gaseous nitrogen is
accomplished by microorganisms in a series of biochemical reactions. The process is known as:Solution
Denitrification is a microbial facilitated process where nitrate is reduced and ultimately produces molecular nitrogen through a series of intermediate gaseous nitrogen oxide products
