Research On The Cultivation of Nitrifying Bacteria And Possibility of The Biomass Storage

Abstract

Bacteria oxidizing ammonium nitrogen to nitrate were first described by Winogradsky in 19 th century [1]. During long-term research different types of nitrification bacteria oxidizing ammonia nitrogen and nitrite were distinguished. Ammonia oxidizing bacteria (archea) (AOB and AOA) constitute e.g.: Nitrosomonas europaea / Nitrosococcus mobilis, Nitrosomonas communis, Nitrosomonas marina, Nitrosomonas oligotropha, Nitrosomonas cryotolerans, Nitrosomonas sp., Nitosococcus sp., Nitrocistis oceanus and to nitrite oxidising bacteria belong Nitrobacter sp., Nitrococcus sp., Nitrospira sp., Nitrospina sp. [1]. Until now, no bacteria have been able to carry out completely the two processes of nitrification. Bacteria of the Nitroso-(Nitrosospira sp., Nitrosolobus sp., Nitrosovibrio sp. and Nitrosococcus sp.
