Chryseobacterium shandongense sp. nov., isolated from soil.

YF-3T is a Gram-stain-negative, non-motile, non-spore-forming, yellow-orange, rod-shaped bacterium. Optimal growth conditions were at 30 °C, pH 7.0 and 1 % (w/v) NaCl. Phylogenetic analysis, on the basis of the 16S rRNA gene sequence, showed that strain YF-3T was closely related to the strains Chryseobacterium hispalense AG13T and Chryseobacterium taiwanense Soil-3-27T with 98.71 % and 96.93 % sequence similarity, respectively. Strain YF-3T contained MK-6 as the main menaquinone and had a polyamine pattern with sym-homospermidine as the major component. Its major polar lipid was phosphatidylethanolamine. The dominant fatty acids of strain YF-3T were iso-C15 : 0, iso-C17 : 0 3-OH, summed feature 9 (comprising iso-C17 : 1ω9c and/or C16 : 0 10-methyl) and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). The DNA G+C content of strain YF-3T was 37 mol%. The DNA-DNA relatedness levels between strain YF-3T and the most closely related strains, C. hispalense AG13T and C. taiwanense Soil-3-27T, were 31.7 ± 2.1 % and 28.4 ± 5.4 %, respectively. Based on these results, a novel species named Chryseobacterium shandongense sp. nov. is proposed. The type strain is YF-3T ( = CCTCC AB 2014060T = JCM 30154T).
