Cohnella fontinalis sp nov., a xylanolytic bacterium isolated from fresh water

A novel xylan-degrading bacterium, VT-1101(T), was isolated from fresh water. The isolate was a Gram-reaction-negative, aerobic, motile, endospore-forming and rod-shaped bacterium. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain YT-1101(T) belonged to the genus Cohnella, sharing sequence similarities of less than 94% with the type species. The genomic G+C content was 58.6 mol%. The predominant menaquinone was MK-7. The major fatty acids were anteiso-C-15:0, iso-C-16:0 and iso-C-15:0. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. On the basis of morphological, physiological and phylogenetic properties, strain YT-1101(T) represents a novel species of the genus Cohnella, for which the name Cohnella fontinalis sp. nov. is proposed. The type strain is VT-1101(T) (=NBRC 104957(T) =DSM 21753(T)).
