Abstract

|
A white-coloured bacterium, SGM1-15T, was isolated from a paddy soil sample from Suwon, Republic of Korea. The cells were strictly aerobic, Gram-negative and curved rod-shaped. A phylogenetic analysis based on 16S rRNA gene sequences revealed that strain SGM1-15T was closely related to Curvibacter delicatus LMG 4328T (97.6% similarity) and Caenimonas koreensis EMB320T (97.5% similarity). The major respiratory quinone system was Q-8 and the predominant cellular fatty acids were C16:0 (39.9%), summed feature 3 (C16:1ω7c and/or iso-C15:0 2-OH; 24.3%) and C17:0 cyclo (22.7%). The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. The major polyamines were 2-hydroxypurescine, purescine and spermidine. The DNA G+C content was 68.7 mol%. On the basis of the phylogenetic, physiologicl and chemotaxonomic data, stain SGM1-15T represents a novel species of the genus Caenimonas, for which the name Caenimonas terrae sp. nov. is proposed. The type strain of Caenimonas terrae is SGM1-15T (=KACC 13365T =NBRC 106341T).
