title: Flaviaesturariibacter amylovorans gen. nov., sp. nov., a starch-hydrolysing bacterium, isolated from estuarine water.
abstract: A novel bacterial strain, designated GCR0105(T), was isolated from a water sample of the Mangyung estuary enclosed by the Saemangeum Embankment, located in JEOLlabuk-do, South Korea. Cells of strain GCR0105(T) were Gram-stain-negative, non-motile and rod-shaped. Colonies of strain GCR0105(T) were pale yellow-pigmented on R2A agar and nutrient agar media, and were able to grow at 15-30 °C (optimum 25 °C) and pH 6.5-8.5 (optimum pH 7.5). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain GCR0105(T) was related most closely to Flavisolibacter ginsengisoli Gsoil 643(T) (93.14% similarity). The polar lipid profile of strain GCR0105(T) comprised phosphatidylethanolamine, two unknown aminolipids, an unknown aminophospholipid and four unknown lipids. The DNA G+C content of strain GCR0105(T) was 42.9 mol% and the respiratory quinone was MK-7.On the basis of phenotypic, chemotaxonomic and phylogenetic properties, strain GCR0105(T) represents a novel species in a new genus within the family Chitinophagaceae, for which the name Flaviaesturariibacter amylovorans gen. nov., sp. nov. is proposed. The type strain of Flaviaesturariibacter amylovorans is GCR0105(T) ( = KACC 16454(T) = JCM 17919(T)).
