Title Komagataeibacter diospyri sp. nov., a novel species of thermotolerant bacterial nanocellulose-producing bacterium.
Journal Int J Syst Evol Microbiol
Abstract Thermotolerant bacterial nanocellulose-producing strains, designated MSKU 9T and MSKU 15, were isolated from persimmon and sapodilla fruits, respectively. These strains were aerobic, Gram-stain-negative, had rod-shaped cells, were non-motile and formed white-cream colonies. Phylogeny based on the 16S rRNA gene sequences revealed that MSKU 9T and MSKU 15 represented members of the genus Komagataeibacter and formed a monophyletic branch with K. swingsii JCM 17123T and K. europaeus DSM 6160T. The genomic analysis revealed that overall genomic relatedness index values of MSKU 9T with K. swingsii JCM 17123T and K. europaeus DSM 6160T were ~90 % average nucleotide identity (ANI) and ≤58.2 % digital DNA-DNA hybridization (dDDH), respectively. MSKU 9T and MSKU 15 can be differentiated from the closely related K. swingsii JCM 17123T by their growth on 30 % d-glucose and ability to utilize and to form acid from raffinose and sucrose as carbon sources, and from K. europaeus DSM 6160T by their ability to grow without acetic acid. The genomic DNA G+C contents of MSKU 9T and MSKU 15 were 60.4 and 60.2 mol%, respectively. The major fatty acids of MSKU 9T and MSKU 15 were summed feature 8 (C18 : 1ω7c and/or C18  : 1ω6c). The respiratory quinone was determined to be Q10. On the basis of the results of the polyphasic taxonomic analysis, MSKU 9T (=TBRC 9844T=NBRC 113802T) represents a novel species of the genus Komagataeibacter, for which the name Komagataeibacterdiospyri sp. nov. is proposed.
