A Gram-staining-negative, strictly aerobic, non-motile, rod-shaped and flexirubin-type-pigmented strain, THG C4-1 T , was isolated from green tea leaves in Jangheung-gun, Republic of Korea. Strain THG C4-1 T grew well at 20-30 6C, at pH 7.0-7.5 and in the absence of NaCl on nutrient agar. Based on 16S rRNA gene sequence comparisons, strain THG C4-1 T was most closely related to Chryseobacterium taiwanense Soil-3-27 T (97.7 %), C. hagamense RHA2-9 T (97.2 %), C. gregarium P 461/12 T (97.2 %), C. ginsenosidimutans THG 15 T (97.1 %), C. taeanense PHA3-4 T (97.0 %) and C. daeguense K105 T (97.0 %), but DNA-DNA relatedness between strain THG C4-1 T and its closest phylogenetic neighbours was below 21 %. The DNA G+C content was 41.7 mol%. The only isoprenoid quinone detected in strain THG C4-1 T was menaquinone 6 (MK-6). The major component of the polyamine pattern was sym-homospermidine. The major polar lipids were phosphatidylethanolamine and unidentified aminolipids. The major fatty acids were iso-C 15 : 0 , iso-C 17 : 0 3-OH and iso-C 17 : 1 v9c. These data supported the affiliation of strain THG C4-1 T to the genus Chryseobacterium. The results of physiological and biochemical tests enabled strain THG C4-1 T to be differentiated genotypically and phenotypically from recognized species of the genus Chryseobacterium. Therefore, the novel isolate represents a novel species, for which the name Chryseobacterium camelliae sp. nov. is proposed, with THG C4-1 T (5KACC 16985 T 5JCM 18745 T ) as the type strain.The genus Chryseobacterium (family Flavobacteriaceae, phylum Bacteroidetes) was described by Vandamme et al. (1994). The description of the genus has since been emended by Tai et al. (2006), Weon et al. (2008) and Kämpfer et al. (2009). The common characteristics of the genus Chryseobacterium include Gram-negative-staining reaction, flexirubin-type pigments, menaquinone 6 (MK-6) as the major predominant respiratory quinone, branched-chain fatty acids iso-C 15 : 0 , iso-C 17 : 0 3-OH and iso-C 17 : 1 v9c as the major fatty acids, sym-homospermidine as the major polyamine and a DNA G+C content of 29-39 mol% (Vandamme et al., 1994; Kämpfer et al., 2009;Bernardet et al., 2010). The membership of the genus has been growing rapidly, as demonstrated by the multitude of novel species that have been proposed in recent years. At the time of writing, the genus Chryseobacterium contains 72 species isolated from various environments such as soils (Weon et al., 2008), fresh water (Strahan et al., 2011), sewage and wastewater (Kämpfer et al., 2003), compost (Kämpfer et al., 2010, the plant rhizosphere (Park et al., 2006), diseased fish (Bernardet et al., 2005), meat (de Beer et al., 2005) and dairy environments (Hugo et al., 2003). In this study, we report the taxonomic characterization of a novel member of the genus Chryseobacterium, strain THG C4-1 T . The taxonomic position of strain THG C4-1 T was determined precisely by using a polyphasic approach.Strain THG C4-1 T was isolated from leaves of green tea (Camellia sinensis) a...
