- Abstract
A Gram-stain negative, strictly aerobic, rod-shaped, non-motile bacterium, designated strain DY46, was isolated from Atlantic Ocean sediment. The isolate was found to grow in medium containing 0-3.0 % (w/v) NaCl (optimally at 0-1.0 %), at 4-37 °C and pH 5.0-8.0. Chemotaxonomic analysis detected MK-6 as the sole isoprenoid quinone. The major fatty acids were identified iso-C, iso-C 3-OH, iso-C ω9c and summed feature 3 (comprising iso-C 2-OH and/or C ω7c). The DNA G + C content was determined to be 40.7 mol %. Phylogenetic analyses based on the 16S rRNA gene sequence indicated that strain DY46 falls within the cluster comprising Chryseobacterium species. The levels of 16S rRNA gene sequence similarity between strain DY46 and the type strains of the Chryseobacterium species with validly published names ranged from 92.4 to 99.1 %, the high values (>97 %) being with Chryseobacterium takakiae A1-2 (99.1 %), C. taiwanense BCRC 17412 (98.0 %), C. taeanense PHA3-4 (97.3 %), C. hispalense DSM 25574 (97.3 %), C. camelliae THG C4-1 (97.2 %), C. gregarium DSM 19109 (97.1 %) and C. wanjuense R2A10-2 (97.0 %). The DNA-DNA relatedness values between strain DY46 and the type strains of the above closely related species were 47, 57, 24, 34, 6, 40 and 21 %, respectively. On the basis of phenotypic and genotypic characteristics, strain DY46 represents a novel member within the genus Chryseobacterium, for which the name Chryseobacterium profundimaris is proposed. The type strain is DY46 (=CGMCC 1.12663 = JCM 19801).
