Preliminary characterization based on 16S rRNA gene sequence analysis showed that WH0801T shared 96.1 % similarity with Agarivorans albus MKT 106T, the type species of the genus Agarivorans. A polyphasic taxonomic study was conducted and confirmed the phylogenetic affiliation of strain WH0801T to the genus Agarivorans. Isolate WH0801T produces light-yellow-pigmented colonies; cells are Gram-stain-negative, straight or curved rods, which are motile with a single polar flagellum. Strain WH0801T grew in 0.5–5 % NaCl, with optimum growth at 3 % NaCl, and its optimal pH and cultivation temperature were 8.4–8.6 and 28–32 °C, respectively. Data from biochemical tests, whole-cell fatty acid profiling, 16S rRNA gene sequence studies and DNA–DNA hybridization clearly indicated that isolate WH0801T represented a novel species within the genus Agarivorans, for which the name Agarivorans gilvus sp. nov. is proposed. The type strain of Agarivorans gilvus sp. nov. is WH0801T (=NRRL B-59247T =CGMCC 1.10131T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.019810-0
