It was observed that chemolithotrophic bacteria of Nitrosomonas genus oxidising ammonia nitrogen may use ammonium as a donor of electrons andsimultaneously oxygen and nitrite as electron acceptors. The products of ammonia nitrogenoxidation, except nitrates, are hydroxylamine, nitrogen oxides and molecular nitrogen. Mechanisms of the process are presented. The process of heterotrophic nitrification is characterised.Factors stimulating the process of simultaneous nitrification and denitrification in activatedsludge as well as the stoichiometry and reaction kinetics of the process were analysed. Finally,the currently emerging research trends were presented.}, title={Mechanizmy i kinetyka nitryfikacj ii denitryfikacji w warunkach niskiego stężenia tlenu rozpuszczonego}, type={Text}, URL={http://www.rcin.org.pl/Content/142821/PDF/POZN271_178149_biotechnologia-1999-no2-klimiuk.pdf}, keywords={biotechnology}, }
