Growth occurred at 15–37 °C and pH 6.0–8.0 without NaCl. The 16S rRNA gene sequence analyses showed that strain 18x22-1T was closely related to Ramlibacter tataouinensis DSM 14655T (98.5 %), followed by Ramlibacter henchirensis DSM 14656T (97.9 %) and other Ramlibacter species and formed a stable cluster with R. tataouinensis DSM 14655T, R. henchirensis DSM 14656T, Ramlibacter solisilvae JCM 19319T and Ramlibacter rhizophilus CCTCC AB 2015357T. Results of chemotaxonomic analyses showed that ubiquinone-8 (Q-8) was the major respiratory quinone, and the major fatty acids (>10 % of the total amounts) were C16 : 0 and C17 : 0cyclo. The major polar lipids were phosphatidylglycerol, diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylcholine, two unidentified aminopholipids and four unidentified phospholipids. The draft genome sequence was 4.47 Mb long with a G+C content of 68.9 mol%. The average nucleotide identity and digital DNA–DNA hybridization values between strain 18x22-1T and four closely related type strains were in the range of 79.3–82.3 % and 21.9–25.1 %, respectively. The results of phenotypic, phylogenetic and chemotaxonomic analyses supported that strain 18x22-1T represents a novel species of the genus Ramlibacter , for which the name Ramlibacter humi sp. nov. is proposed. The type strain is 18x22-1T (=GDMCC 1.1584T=KCTC 52922T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.003641
