Kaistia terrae sp. nov., isolated from a wetland in Korea

An ivory-coloured bacterium, designated strain 5YN7-3(T), was isolated from a wetland, Yongneup, Korea. Cells of the strain were aerobic, Gram-stain-negative, non-motile and short rods. 16S rRNA gene sequence analysis demonstrated that strain 5YN7-3(T) belongs to the order Rhizobiales of the class Alphaproteobacteria and is closely related to Kaistia soli 5YN9-8(T) (97.8 %), Kaistia granuli Ko04(T) (97.6 %) and Kaistia adipata Chj404(T) (97.4 %). Strain 5YN7-3(T) showed DNA-DNA hybridization values of 28, 22 and 35 % with K. granuli Ko04(T), K. soli 5YN9-8(T) and K. adipata Chj404(T), respectively. The major fatty acids were C(18 : 1)omega7c (51.2 %), C(19 : 0) cyclo omega8c (25.0 %), C(18 : 0) (12.9 %) and C(16 : 0) (10.8 %) (>10 % of total fatty acids). Ubiquinone-10 was the major isoprenoid quinone and the DNA G+C content was 66.5 mol%. The phenotypic characteristics in combination with 16S rRNA gene sequence analysis and DNA-DNA hybridization data clearly define strain 5YN7-3(T) as a novel species of the genus Kaistia, for which the name Kaistia terrae sp. nov. is proposed. The type strain is 5YN7-3(T) (=KACC 12910(T) =DSM 21341(T)).
