A non-motile and rod-shaped bacterium, designated strain WM78T, was isolated from freshwater collected from the Woopo wetland (Republic of Korea). Cells were Gram-stain-negative, aerobic, catalase-positive and oxidase-negative. The major fatty acids were iso-C15 :0, anteiso-C15 :0, C16 :1ω7c and/or C16 :1ω6c and iso-C17 :1 I and/or anteiso-C17 :1 B. The strain contained MK-7 as the major isoprenoid quinone, phosphatidylethanolamine as the major polar lipid and sym-homospermidine as the major polyamine. The genomic DNA G+C content was 62 mol%. A phylogenetic tree based on 16S rRNA gene sequences showed that strain WM78T forms evolutionary lineage within the radiation comprising members of the genus Hymenobacter with Hymenobacter gelipurpurascens Txg1T (97.7 % sequence similarity) as its nearest neighbour. A number of phenotypic characteristics distinguished strain WM78T from related members of the genus Hymenobacter. The evidence presented in this study support the designation of strain WM78T as a representative of a novel species in the genus Hymenobacter for which the name Hymenbactor wooponensis sp. nov. is proposed. The type strain is WM78T ( = KCTC 32528T = JCM 19491T).

A marine bacterial strain, FR1064T, was isolated from a surface seawater sample collected off Jeju Island, South Korea. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the isolate belonged to the Gammaproteobacteria and was related to the genus Glaciecola with 97.6 % sequence similarity to Glaciecola pallidula, its nearest phylogenetic neighbour. DNA–DNA relatedness between strain FR1064T and G. pallidula ACAM 615T was 55 %. Cells of the novel isolate were Gram-negative, aerobic, rod-shaped, motile and halophilic, with an optimum sea salts concentration of 4–7 %. The major fatty acids were straight-chain saturated (C16 : 0), summed feature 3 and monounsaturated fatty acid C18 : 1. The DNA G+C content was 44 mol%. Several phenotypic characteristics differentiated the novel isolate from all previously described members of the genus Glaciecola. The polyphasic data obtained in this study clearly demonstrate that strain FR1064T represents a novel species of the genus Glaciecola.

Abstract A Gram-stain-positive, aerobic, non-motile actinobacterium, designated strain YIM 93776T, was isolated from a saline sediment sample collected from Aiding Lake in Xinjiang Uygur Autonomous Region, Northwest China. Phylogenetic analysis based on the 16S rRNA gene sequences showed that strain YIM 93776T was affiliated to the genus Glycomyces, and was closely related to Glycomyces albus TRM 49136T (97.6 % sequence similarity), Glycomyces lacisalsi XHU 5089T (97.0 %) and Glycomyces anabasis EGI 6500139T (96.2 %). The cell wall contained meso-diaminopimelic acid and the whole-cell hydrolysates sugars were galactose, mannose, arabinase, glucose and ribose. The predominant menaquinones were MK-9 (H4) and MK-10 (H4). Diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, two phosphatidylglyceride, two unidentified phospholipids and two unidentified polar lipids were detected in the polar lipid extracts. Major fatty acids were anteiso-C17:0, iso-C15:0, iso-C16:0, anteiso-C15:0 and anteiso C17:1 A. The draft genome sequence of strain YIM 93776T was 5.37 Mbp in size with 69.5 mol% DNA G+C content. On the basis of morphological, chemotaxonomic and phylogenetic evidence, strain YIM 93776T therefore represents a novel species, for which the name Glycomyces salinus sp. nov. is proposed. The type strain is YIM 93776T (= KCTC 49430T = CGMCC 4.7685T).
