Abstract

In , vol. 1, only one species is listed in the genus . One other species, , was proposed by Yamada and Akita in 1984. However, recent deoxyribonucleic acid-deoxyribonucleic 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. Three tests were useful in differentiating the three 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 (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 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 sp. nov.
