denitrification

Examples of denitrification in the following topics:

• The Nitrogen Cycle

  • This process occurs in three steps in terrestrial systems: ammonification, nitrification, and denitrification.
  • Third, the process of denitrification occurs, whereby bacteria, such as Pseudomonas and Clostridium, convert the nitrates into nitrogen gas, allowing it to re-enter the atmosphere.
  • A similar process occurs in the marine nitrogen cycle, where the ammonification, nitrification, and denitrification processes are performed by marine bacteria.

• The Role of Prokaryotes in Ecosystems

  • The bacteria perform the reverse process, the reduction of nitrate from the soils to gaseous compounds such as N2O, NO, and N2, a process called denitrification.
