Abstract
Strain DCY 63T, isolated from the rhizosphere of ginseng, was a Gram-reaction-negative, strictly aerobic, non-motile, catalase- and oxidase-positive rod. 16S rRNA gene sequence analysis revealed that strain DCY 63T belonged to the genus
Chryseobacterium
and was closely related to
Chryseobacterium indoltheticum
LMG 4025T (98.1 %),
Chryseobacterium ginsenosidimutans
THG 15T (98.0 %) and
Chryseobacterium scophthalmum
LMG 13028T (97.1 %). The major polar lipids of strain DCY 63T were phosphatidylethanolamine (PE), four unidentified aminolipids and three unidentified polar lipids, and the major fatty acids were iso-C15 : 0, iso-C17 : 0 3-OH, summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) and summed feature 9 (iso-C17 : 1ω9c and/or C16 : 0 10-methyl). The predominant isoprenoid quinone of strain DCY 63T was MK-6 and the G+C content of the genomic DNA was 31.6 mol%. The DNA–DNA relatedness values between strain DCY 63T and
C. indoltheticum
LMG 4025T,
C. ginsenosidimutans
THG 15T and
C. scophthalmum
LMG 13028T were less than 30 %. On the basis of these data, strain DCY 63T is considered to represent a novel species of the genus
Chryseobacterium
, for which the name
Chryseobacterium
ginsengisoli sp. nov. is proposed. The type strain is DCY 63T ( = KCTC 23760T = JCM 18019T). An emended description of
Chryseobacterium gleum
is also proposed.
