( 2014 ) Chryseobacterium oleae sp. nov., an efficient plant growth promoting bacterium in the rooting induction of olive tree (Olea europaea L.) cuttings and emended descriptions of the genus Chryseobacterium, C. daecheongense, C. gambrini, C. gleum, C. joostei, C. jejuense, C. luteum, C. shigense, C. taiwanense, C. ureilyticum and C. vrystaatense. PMID : 24867808 DOI : 10.1016/j.syapm.2014.04.004 Abstract >>
A novel non-motile, Gram-staining-negative, yellow-pigmented bacterium, designated CT348(T), isolated from the ectorhizosphere of an organic olive tree in Spain and characterised as an efficient plant growth promoting bacterium, was investigated to determine its taxonomic status. The isolate grew best in a temperature range of 5-35�XC, at pH 5.0-8.0 and with 0-1% (w/v) NaCl. Chemotaxonomic and molecular characteristics of the isolate matched those described for members of the genus Chryseobacterium. The DNA G+C content of the novel strain was 38.2mol%. The strain contained a polyamine pattern with sym-homospermidine as the major compound and produced flexirubin-type pigments. MK-6 was the dominant menaquinone and the major cellular fatty acids were iso-C15:0, C17:1�s9c, iso-C17:0 3-OH and iso-C15:0 2-OH. The main polar lipids were phosphatidylethanolamine and several unidentified lipids and aminolipids. The 16S rRNA gene showed 92.2-97.8% sequence identity with the members of the genus Chyseobacterium. Based on the phenotypic traits and DNA-DNA hybridizations with the type strains of the most closely related species, the isolate is shown to represent a novel species, Chyseobacterium oleae, type strain CT348(T) (=DSM 25575 =CCUG 63020). Emended descriptions of the genus Chryseobacterium and C. daecheongense, C. gambrini, C. gleum, C. joostei, C. jejuense, C. luteum, C. shigense, C. taiwanense, C. ureilyticum and C. vrystaatense are also proposed.

( 2006 ) Chryseobacterium taiwanense sp. nov., isolated from soil in Taiwan. PMID : 16902006 DOI : 10.1099/ijs.0.64294-0 Abstract >>
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 soil 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 to the genus Chryseobacterium. The organism contains menaquinone MK-6 as the predominant isoprenoid quinone and 15 : 0 iso (43 %), 17 : 1 isoomega9c (17.5 %) and 17 : 0 iso 3-OH (16.6 %) 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 relatedness 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 strain Soil-3-27(T) (=BCRC 17412(T)=IAM 15317(T)=LMG 23355(T)).
