sp. nov., isolated from tropical forest soil.

A Gram-stain-negative, aerobic and non-motile strain, designated 18x22-1, was isolated from a forest soil sample collected from Limushan Nature Reserve in Hainan Province, PR China. Growth occurred at 15-37 °C and pH 6.0-8.0 without NaCl. The 16S rRNA gene sequence analyses showed that strain 18x22-1 was closely related to DSM 14655 (98.5 %), followed by DSM 14656 (97.9 %) and other species and formed a stable cluster with DSM 14655, DSM 14656, JCM 19319 and s CCTCC AB 2015357. 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 C and Ccyclo. 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 18x22-1 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 18x22-1 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is 18x22-1 (=GDMCC 1.1584=KCTC 52922).
