Cells are spherical (coccus). Gram-stain negative. Gram-negative cell structure. Cells have thin layer of extracellular slime and buds or appendages around the cells. Nonmotile. Strictly aerobic, chemoheterotrophic, and facultatively oligotrophic bacteria. Do not produce pigments. Require NaCl for growth. Do not utilize amino acids as sole carbon sources. Produce transparent exopolymers. The major cellular fatty acids are C16:1 ω9c (50.8%) and C14:0 (25.9%). The genome size is 6.02 Mb, based on full-genome sequencing. Phylogenetically, the genus belongs to the order Lentisphaerales in the phylum Lentisphaerae.
