| Abstract: | During a previous study on the molecular interaction between commensal bacteria and host gut immunity, two novel bacterial strains, A911T and G707T, were isolated from the gut of Drosophila melanogaster. In this study, these strains were characterized in a polyphasic taxonomic study using phenotypic, genetic, and chemotaxonomic analyses. We show that the strains represent novel species in the family Acetobacteraceae. Strain G707T, a highly pathogenic organism, represents a new species in the genus Gluconobacter, “Gluconobacter morbifer” sp. nov. (type strain G707 = KCTC 22116T = JCM 15512T). Strain A911T, dominantly present in the normal Drosphila gut community, represents a novel genus and species, designated “Commensalibacter intestini” gen. nov., sp. nov. (type strain A911 = KCTC 22117T = JCM 15511T). |
