In nitrification, ammonium is oxidised to nitrite by

  • A.Nitrosomonas
  • B.Nitrobacter
  • C.Pseudomonas
  • D.Azotobacter

Answer: A

Nitrification runs in two steps carried out by different genera: Nitrosomonas takes ammonium to nitrite, and only then does Nitrobacter take nitrite to nitrate. Confusing the two is easy because the names are similar, so it helps to note that nitrite comes first alphabetically and from NitroSOmonas.
