“…In particular, the results for citrate utilization and gelatin hydrolysis were shown to be the same, irrespective of the API strips used (Table S4). In addition, some type strains of species of the genus Rahnella showed different results from those previously reported [3, 5] for the Voges–Proskauer reaction, activity of arginine dihydrolase and acid production from a few substrates ( and S4), which might be caused by misreading results or data entry errors. Strains SAP-17 T , SAP-29 and Lac-M12 differed from Lac-M11 T in acid production from d -arabitol, methyl α- d -mannoside, d -sorbitol and 5-ketoglutarate, and by the presence of esterase (C4) and α-glucosidase, whereas the above four isolates were differentiated from strain SAP-10 by acid production from methyl α- d -mannoside, d -sorbitol and 5-ketoglutarate, and by the presence of N -acetyl-β-glucosamidase.…”

“…In addition, the six type strains of Rahnella species had two or three unidentified phospholipids depending on the strain, which were absent in the isolates (SAP-17 T , Lac-M11 T and SAP-10) and R. aceris [5], whereas strains SAP-29 and SAP-10 contained unidentified lipids (Fig. S3b, c), as in R. aceris [5]. Interestingly, strain SAP-10, albeit being a strain of R. victoriana, did not contain any phospholipid, in contrast to R. victoriana KACC 19480 T having three unidentified phospholipids (Fig.…”

“…The 16S rRNA gene sequences of the six isolates were determined as previously described [5], with genomic DNA prepared using Wizard Genomic DNA Purification Kit (Promega) according to the manufacturer's instructions and contained 1480-1486 nucleotides depending on strains. The 16S rRNA gene sequence similarities obtained using the dnasis program (version 6.…”

“…Tree sap was collected through a long tube (6–9 mm in diameter) connected with the inserted valves and stored at −70 °C before use. The medium and procedure for bacterial isolation were as previously described [5]. Two other strains were isolated from the plates of MRSA medium (Lactobacilli MRS agar; Difco) stored for about 1 month at 5 °C after the isolation of Lactobacillus strains were performed under anaerobic conditions with traditional raw rice wine commercially released in Jeju in May 2019.…”

“…The core gene-based phylogenomic tree () revealed that the four isolates formed three independent sublines within the genus Rahnella with a 100 % gene support index. Also, all the genera of the family Yersiniaceae were shown to be monophyletic, in contrast to the 16S rRNA gene phylogeny, showing the polyphyletic relationships of some genera [5, 17, 18]. Strains SAP-17 T , SAP-29 and Lac-M12 shared ANI values of 97.4–100 % with one another, supporting that they are strains of the same species, whereas the ANI and dDDH values between them and strain Lac-M11 T were 95.0 and 60.8 %, respectively.…”

Taxonomic positions of six isolates, which were recovered from two different environments in Jeju, Republic of Korea, were examined by a polyphasic analysis. Cells of the isolates were Gram-reaction-negative, facultatively anaerobic, motile and rod-shaped and showed growth at 4–30 °C, pH 4.0–9.0 and with 0–6 (w/v) NaCl. In phylogenomic analysis based on 92 single-copy core genes, it was shown that the isolates belonged to the genus Rahnella and formed three distinct sublines within the genus. The isolates shared 16S rRNA gene sequence similarities of 97.9–100 % with one another. The isolates contained ubiquinone-8 was as the major isoprenoid quinone. The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and an unidentified aminophospholipid. The predominant fatty acids were C16 : 0 and C17 : 0 cyclo. The G+C content of their genomic DNA was 52.8–53.1 %. Average nucleotide identity and digital DNA–DNA hybridization values supported that strains SAP-17T and Lac-M11T represented two new species of the genus Rahnella , whereas strain SAP-10 was a strain of Rahnella victoriana . Based on the results obtained here, Rahnella laticis sp. nov. (type strain SAP-17T=KCTC 72960T=NBRC 114723T=CCM 9079T) and Rahnella contaminans sp. nov. (type strain Lac-M11T=KACC 21743T=NBRC 114406T) are proposed. Also, an emended description of the genus Rahnella is given on the basis of our physiological and chemotaxonomic results.
