abstract= An acetic acid bacterium (strain Bo7T), obtained during a study of the microbial diversity of spontaneous fermentations of Bobal grape must, was subjected to a taxonomic study using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences allocated strain Bo7T to the genus Acetobacter, and revealed Acetobacter aceti and Acetobacter oeni to be nearest neighbours (99.57 % 16S rRNA gene sequence similarity between strain Bo7T and A. oeni CECT 5830T, and 98.76 % between strain Bo7T and A. aceti CECT 298T). Cells of strain Bo7T are Gram-negative, motile rods, catalase-positive and oxidase-negative. The DNA G+C content of strain Bo7T was 58.0 mol%. DNA–DNA hybridizations demonstrated that strain Bo7T belongs to a single novel genospecies that can be differentiated from its nearest phylogenetic neighbours by the following phenotypic characteristics: no production of 5-keto-d-gluconic acid from d-glucose, growth with glycerol but not with methanol or maltose as sole carbon sources, and growth on yeast extract with 30 % d-glucose. The major fatty acid was C18 : 1ω7c/C18 : 1ω6c (summed feature 8; approx. 56 %); other fatty acids in significant amounts (>5 %) were C16 : 0 2-OH (11 %), C16 : 0 (7 %), C14 : 0 2-OH (7 %) and C14 : 0 3-OH/iso-C16 : 1 I (summed feature 2; 6 %). The results obtained indicate that strain Bo7T represents a novel species of the genus Acetobacter, for which the name Acetobacter musti sp. nov. is proposed. The type strain is Bo7T ( = DSM 23824T = CECT 7722T).,
