Chryseobacterium taiwanense sp nov., isolated from soil in Taiwan

Among a large collection of Taiwanese soil isolates, a novel Gram-negative, rod-shaped, non-spore-forming, yellow-pigmented bacterial strain, Soil-3-27(T,) was isolated from farmland in Wu-Feng, Taiwan. The isolate was subjected to a polyphasic study including 16S rRNA gene sequencing, DNA-DNA hybridization, fatty acid analysis and comparative phenotypic characterization. The 16S rRNA gene sequence analysis indicated that the organism belongs the genus Chryseobacterium. The organism contains menaquinone MK-6 as the predominant isoprenoid quinone and 15: 0 iso (43%), 17:1 iso omega 9c (117-5%) and 17: 0 iso 3-OH (116-6%) as the major fatty acids. Phylogenetically, the closest relatives of strain Soil-3-27(T) are Chryseobacterium daecheongense, Chryseobacterium defluvii and Chryseobacterium taichungense with 96-7-97-2 % sequence similarity. DNA-DNA hybridization showed values of 8-5-24-2 % with these species. The DNA G + C content is 36(.)8 mol%. Strain Soil-3-27(T) is clearly distinguishable from other Chryseobacterium species and represents a novel species, for which the name Chryseobacterium taiwanense sp. nov. is proposed. The type strain is Soil-3-27(T) (=BCRC 17412(T) = IAM 15317(T) =LMG 23355(T)).
