Limibacter armeniacum gen. nov., sp. nov., a novel representative of the family 'Flammeovirgaceae' isolated from marine sediment.

Two strictly aerobic, Gram-negative, gliding, apricot- to pale-orange-pigmented, rod-shaped bacteria, strains YM11-185T and YM11-159, were isolated from marine sediments in the Republic of Palau. Preliminary analysis based on the 16S rRNA gene sequence revealed that the novel isolates could be affiliated with the family 'Flammeovirgaceae' of the phylum Bacteroidetes. Strains YM11-185T and YM11-159 shared 100 % sequence similarity and showed less than 90 % similarity to cultivated representatives of the family 'Flammeovirgaceae'. The novel isolates are phenotypically and physiologically different from strains described previously. The G+C content of DNA was 27.8-27.9 mol%, MK-7 was the major menaquinone and iso-C15 : 0 and C16 : 1 omega 7c were the major fatty acids. On the basis of polyphasic taxonomic studies, it was concluded that strains YM11-185T and YM11-159 represent a novel species in a new genus of the family 'Flammeovirgaceae', for which the name Limibacter armeniacum gen. nov., sp. nov. is proposed. The type strain of Limibacter armeniacum is YM11-185T (=MBIC08286T =KCTC 22132T).
