Abstract
A Gram-reaction-negative, strictly aerobic, betaproteobacterial strain, designated SAP-35T, was isolated from sap extracted from Acer pictum in Mt. Halla in Jeju, Republic of Korea, and its taxonomic status was examined by a polyphasic approach. Cells of the organism were non-sporulating, motile rods and grew at 4-30 °C, pH 6-7 and in the absence of NaCl. 16S rRNA gene- and whole genome-based phylogenetic analyses showed that strain SAP-35T belonged to the family Oxalobacteraceae and was closely related to Rugamonas rivuli (98.9% 16S rRNA gene sequence similarity) and Rugamonas aquatica (98.4%). The phylogenomic clustering and average amino acid identity values supported that strain SAP-35T belonged to the genus Duganella and two Rugamonas species should be transferred to the genus Duganella. The major isoprenoid quinone of the isolate was Q-8. The major polar lipids were phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol and an unidentified aminophospholipid. The predominant fatty acids were summed feature 3, C16:0 and C17:0 cyclo. The G + C content of genome was 64.9%. The average nucleotide identity and dDDH values between strain SAP-35T and the members of the genera Rugamonas and Duganella were < 85.1% and < 49%, respectively. Based on the combined data presented here, strain SAP-35T (= KCTC 72227T = NBRC 113903T) represents a novel species of the genus Duganella, for which the name Duganella aceris sp. nov. is proposed. Also, Rugamonas aquatica Lu et al. (Int J Syst Evol Microbiol 70: 3328-3334, 2020) and Rugamonas aquatica Lu et al. 2020 are reclassified as Duganella aquatica comb. nov., with the emended description of the genus Rugamonas.
