Flavobacterium gilvum sp. nov., isolated from stream water

A cream-coloured, non-gliding, aerobic Flavobacterium strain, designated EM1308 T , was isolated from stream water. 16S rRNA gene sequence analysis indicated that this isolate is closely related to Flavobacterium glycines NBRC 105008 T (97.3 % similarity) and Flavobacterium piscis CCUG 60099 T (97.2 %). To evaluate the genomic relatedness of the isolate with its neighbours, the whole genome sequences of strain EM1308 T and the type strains of F. glycines and F. piscis were determined. Average nucleotide identities revealed that strain EM1308 T is independent from other Flavobacterium species. The properties of major cellular fatty acids, polar lipids, menaquinone and DNA G+C content of the isolate were within the general range for the genus Flavobacterium , but many biochemical and physiological characteristics distinguished the isolate from previously known species. Thus, strain EM1308 T represents a novel species of the genus Flavobacterium , for which the name Flavobacterium gilvum sp. nov. is proposed. The type strain is EM1308 T (=KACC 18113 T =JCM 30144 T ).
