Removal of ammonia by immobilizaed Nitrosomonas europaea in a biotrickling filter packed with polyurethane foam [PDF]

, 2007
[Abstract] A chemolithoautrotrophic microorganism Nitrosomonas europaea has been utilized to remove gaseous ammonia in a biotrickling filter packed with polyurethane foam. The optimal pH for removing was 7.5 and the biological removal efficiency was zero

Sequence of the gene coding for ammonia monooxygenase in Nitrosomonas europaea

Journal of Bacteriology, 1993
Nitrosomonas europaea, a chemolithotrophic bacterium, was found to contain two copies of the gene coding for the presumed active site polypeptide of ammonia monooxygenase, the 32-kDa acetylene-binding polypeptide. One copy of this gene was cloned, and its complete nucleotide sequence is presented. Immediately downstream of this gene, in the same operon,

Whole transcriptome analysis highlights nutrient limitation of nitrogen cycle bacteria in simulated microgravity

npj Microgravity
Regenerative life support systems (RLSS) will play a vital role in achieving self-sufficiency during long-distance space travel. Urine conversion into a liquid nitrate-based fertilizer is a key process in most RLSS.

Novel nirK cluster genes in Nitrosomonas europaea are required for NirK-dependent tolerance to nitrite

, 2005
Nitrite reductase (NirK) of Nitrosomonas europaea confers tolerance to nitrite (NO2-). The nirK gene is clustered with three genes of unknown physiological function: ncgABC. At present, this organization is unique to nitrifying bacteria.
