Abstract
In Bergey''s Manual of Systematic Bacteriology, vol. 1, only one species is listed in the genus Gluconobacter. One other species, Gluconobacter cerinus, was proposed by Yamada and Akita in 1984. However, recent deoxyribonucleic acid-deoxyriboucleic acid homology studies have produced evidence of at least three distinct homology groups that are believed to represent three species within this genus. In this paper we report results obtained by using 35 strains and 58 phenotypic characteristics. There tests were useful in differentiating the three Gluconobacter species. Homology group I strains grew to an optical density (OD) of only 0.5 U or less on medium containing ribitol or arabitol as the primary carbon source, and they grew to an OD of only 0.5 U or less after three passages (24 h of incubation each) in nicotinate-deficient media. We propose that the name Gluconobacter oxydans (Henneberg 1897) De Ley 1961 be retained for these strains. Homology group II strains grew to an OD of more than 1.0 U on medium containing ribitol or arabitol as the primary carbon source, and they grew to an OD of more than 1.0 U after three passages (24 h of incubation each) in nicotinate-deficient media. We propose that the group II gluconobacters be named Gluconobacter frateurii sp. nov. All of the typical strains of homology group III grew to an OD of 0.5 U or less on medium containing ribitol or arabitol as the primary carbon source, but they grew to an OD of 1.0 U or more after three passages (24 h of incubation each) in nicotinate-deficient media. We propose that the group III gluconobacters be named Gluconobacter asaii sp. nov.
