Strain 17mud1-7 T , a pink, aerobic, catalase-positive, oxidase-positive and Gram-reaction-negative bacterium, was isolated from wet mud. The isolate grew aerobically at 18-37 °C (optimum 28 °C), at pH 6.0-8.0 (optimum pH 7.0) and in the presence of 0-1 % (w/v) NaCl (optimum 0 % NaCl). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 17mud1-7 T belonged to the genus Adhaeribacter with highest sequence similarity of 96.4 % to Adhaeribacter aerophilus 6424S-25 T . The strain showed the typical chemotaxonomic characteristics of the genus Adhaeribacter, with the presence of menaquinone MK-7 as the respiratory quinone, and summed feature 4 (composed of iso-C17 : 1 I/anteiso-C17 : 1 B), iso-C15 : 0 and C16 : 1ω5c as the major fatty acids are. The polar lipid profile contained two aminophosphoglycolipids, two glycolipids and three unidentified lipids. The DNA G+C content of strain 17mud1-7 T was 45.9 mol%. Strain 17mud1-7 T should thus be classified as representing a novel species in the genus Adhaeribacter, for which the name Adhaeribacter swui sp. nov. is proposed. The type strain is 17mud1-7 T (=KCTC 52873 T =NBRC 112824 T ).
