Mucilaginibacter jinjuensis sp. nov., with xylan-degrading activity.
A gram-negative, rod-shaped, pale-orange-pigmented bacterial strain with xylan-degrading activity designated YC7004(T) was isolated from a rotten-wood sample collected at Jinju, Korea, and its taxonomic position was investigated by using a polyphasic approach. The strain grew optimally on R2A medium at 30 °C and at pH 6. The major isoprenoid quinone was MK7 and major fatty acids were summed feature 3, iso-C15 : 0, C16 : 0, iso-C17 : 0 3-OH, iso-C17 : 1ω9c and C16 : 1ω5c. The G+C content of the genomic DNA was 40.0 mol%. Phylogenetic analysis based on the 16S rRNA gene sequences showed that the strain belongs to the genus Mucilaginibacter in the family Sphingobacteriaceae. The most closely related species were Mucilaginibacter daejeonensis (95.5 %), Mucilaginibacter frigoritolerans (94.6 %) and Mucilaginibacter mallensis (94.0 %). Based on the phylogenetic and chemotaxonomic data analyses, strain YC7004(T) represents a novel species of the genus Mucilaginibacter with the proposed name of Mucilaginibacter jinjuensis sp. nov. The type strain is YC7004(T) ( = KACC 16571(T) = NBRC 108856(T)).
