A nitrate-reducing bacterium was isolated from a hot spring and identified as Bacillus licheniformis. This strain was found to accumulate NO2(-) in the medium even in the presence of NH4(+) by shaking culture when FeSO4 was added to the medium. The NO2(-) accumulation was due to nitrate reductase activity, and the same accumulation was also recognized in some other bacteria. Since the nitrate reduction had no marked effect on the cell growth, it is possible that this nitrate reduction may not be involved in either an assimilatory or a dissimilatory one like those hitherto reported.
从温泉中分离出一株硝酸盐还原菌，鉴定为地衣芽孢杆菌。当向培养基中添加硫酸亚铁时，通过振荡培养发现该菌株即使在有铵离子存在的情况下也会在培养基中积累亚硝酸根离子。亚硝酸根离子的积累是由于硝酸还原酶的活性，在其他一些细菌中也观察到了同样的积累现象。由于硝酸盐还原对细胞生长没有显著影响，所以这种硝酸盐还原可能不像迄今报道的那样参与同化或异化过程。
