Abstract
The name Bacillus azotoformans (ex Pichinoty, de Barjac, Mandel, Greenway, and Garcia 1976) is revived. Strains of this species are motile and produce terminal or subterminal oval endospores in swollen sporangia. Nitrate, nitrite, and nitrous oxide are denitrified with production of nitrogen. The guanine-plus-cytosine content of the deoxyribonucleic acid of this organism is 39.8 ± 1.2 mol% (mean ± standard deviation). The type strain is ATCC 29788 (= CCM 2849 = CIP R925).
