Ammonia oxidation by Nitrosomonas eutropha with NO(sub)2 as oxidant is not inhibited by acetylene

Article Abstract:

Research examines the aerobic and anaerobic ammonia oxidation in Nitrosomonas eutropha as influenced by the nitrogen oxides, NO and NO(sub)2. Results show that effect of acetylene on the oxidation processes suggest that the dimeric form of NO(sub)2, N(sub)2)(sub)4, is the obligatory oxidant under both oxic and anoxic conditions.

Propionate oxidation by and methanol inhibition of anaerobic ammonium-oxidizing bacteria

Article Abstract:

The effects of organic compounds on the anammox bacteria and the potential for mixotrophic growth were investigated. The result shows that the exposure of anammox bacteria to alcohol, methanol in particular should be prevented under all circumstances.

Biomakers for in situ detection of anaerobic ammonium-oxidizing (anammox) bacteria

Article Abstract:

The advances made in the 16S rRNA gene-based techniques for the detection of anammox bacteria are summarized. The results indicate that for a proper evaluation of the contribution of the anammox process to nitrogen cycling in a particular habitat, the combination of different (rRNA and non-rRNA) methods is necessary.
