A chemolithotrophic ammonium-oxidizing bacterium that was able to reduce NO(2) to N(2) (m/z 30) while oxidizing ammonium under conditions of oxygen stress was isolated from stream sediments. Energy was derived from ammonium oxidation, as evidence by growth, with CO(2) serving as the sole C source. The organism was a gram-negative, motile, short rod that failed to grow either aerobically or anaerobically in heterotroph media. The organism was identified as a Nitrosomonas sp.
从溪流沉积物中分离到一种化能自养氨氧化菌,该菌能够在氧气胁迫条件下将 NO2还原为 N2(m/z 30),同时氧化铵。能量来源于铵氧化,这一点可以通过以 CO2作为唯一碳源的生长来证明。该生物体是革兰氏阴性、运动的短杆菌,在好氧或异养培养基中均不能生长。该生物体被鉴定为亚硝化单胞菌属(Nitrosomonas sp.)。
