A New Species

Two isolates, MS16-SU-2T and MS18-SU-3, obtained from fermented mangosteen peel in vinegar were suggested to constitute a new species assignable to the genus Acetobacter based on the results of 16S rRNA gene sequencing. The two isolates showed the highest sequence similarity (98.58%) to Acetobacter tropicalis NBRC 16470T and Acetobacter senegalensis LMG 23690T. However, the calculated similarity values were lower than the threshold for species demarcation. The phylogenetic analysis showed that the branches of the two isolates were separated from other Acetobacter species, and the two isolates constituted a new species in the genus Acetobacter . The genomic DNA of isolate MS16-SU-2T was sequenced. The assembled genome of the isolate was analysed, and the results showed that the highest average nucleotide identity value of 75.9 % was with Acetobacter papayae JCM 25143T and the highest digital DNA–DNA hybridization value of 25.1 % was with Acetobacter fallax LMG 1636T, which were lower than the cutoff values for species delineation. The phylogenetic tree based on the genome sequences showed that the lineage of isolate MS16-SU-2T was most closely related to A. papayae JCM 25143T and Acetobacter suratthaniensis TBRC 1719T, but separated from the branches of these two species. In addition, the two isolates could be distinguished from the type strains of closely related species by their phenotypic characteristics and MALDI-TOF profiles. Therefore, the two isolates, MS16-SU-2T (=TBRC 12339T=LMG 32243T) and MS18-SU-3 (=TBRC 12305), can be assigned to an independent species within the genus Acetobacter , and the name of Acetobacter garciniae sp. nov. is proposed for the two isolates.

A New Species

The ultrastructure of the cells of the major component of an enriched culture of a presumed methanogen which utilized acetic acid was studied by transmission and scanning election microscopy. The filaments were composed of Gram-positive, rod-shaped cells, 1–2 μm in length and about 0.5 μm in breadth, attached end to end. Septa between cells were complex, with a central, electron-dense sheet which had a spherical enlargement in the center separating the cell walls. The cells walls themselves were of variable thickness with a light, fluffy, thin portion on the outside and a denser, thicker portion within. They contain a series of rings stacked side by side which are composed of material that stains strongly and positively with phosphotungstate ion. The cytoplasmic membrane of these cells had an outer leaflet which stains more densely with uranium and lead ions than the inner leaflet. There were no recognizable organelles in the cytoplasm other than ribosomes. It is shown in these observations that the presumed methanogen may likely be a new species.
