The strain was arginine dihydrolase-positive, and oxidase- and catalase-positive. Growth occurred between 10 and 37 °C, with optimal growth occurring between 30 and 32 °C. Comparative 16S rRNA gene sequence analysis showed its nearest neighbours are members of the genus Kistimonas of the family Hahellaceae , which is found in the order Oceanospirillales , class Gammaproteobacteria . The closest related species was Kistimonas asteriae KMD 001T with 16S rRNA gene sequence similarity of 99.0 %. However, DNA–DNA hybridization between these strains revealed less than 70 % DNA–DNA relatedness, supporting the novel species status of the strain. The major fatty acids were C16 : 0, C18 : 0, C18 : 1ω7c and a summed feature that contained C16 : 1ω6c/C16 : 1ω7c. The major respiratory quinone was ubiquinone-9 and the predominant polar lipids were phosphatidylserine, phosphoethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The genomic DNA G+C content was 52.5 mol%. Based on the data presented, strain BGP-2T is considered to represent a novel member of the genus Kistimonas , for which the name Kistimonas alittae sp. nov. is proposed. The type strain is BGP-2T (=CCUG 65711T=JCM 30010T)., language=, type=
