Nitrobacter winogradskyi transcriptomic response to ammonia


ABSTRACT: The comparison was done in chemostats. Cultures maintained nitrite. The transcritome responses were compared at three ammonium concentrations. The comparison was done in chemostats. Single cultures maintained with 60 mM nitrite, and the ammonium supllemented as appropiate.

Nitrobacter winogradskyi Nb-255 is a nitrite-oxidizing bacterium that can grow solely on nitrite (NO2(-)) as a source of energy and nitrogen. In most natural situations, NO2(-) oxidation is coupled closely to ammonium (NH4(+)) oxidation by bacteria and archaea and, conceptually, N. winogradskyi can save energy using NH4(+) to meet its N-biosynthetic requirements. Interestingly, NH4(+) delayed the growth of N. winogradskyi when at concentrations higher than 35 mM, but grew well at concentrations  ...[more]
