Citromicrobium bathyomarinum-JF-1, the most closely related strain having nonvalidly published name, was 98.4%, followed by 95.2-6.7% identities with sequence of the other closest strains in the genus Erythrobacter. Strain CBA4602T had bacteriochlorophyll a and carotenoids. Strain CBA4602T grew in 0-0% (w/v) NaCl, at 10-2°C and pH 6.0-.0, with optimal growth in 1-% NaCl, at 30-7°C and pH 7.0. Strain CBA4602T was positive for catalase and oxidase activities and was able to hydrolyse gelatine and Tween 20 and 40, but not starch, Tween 80 or l-tyrosine. The G+C content of genomic DNA from strain CBA4602T was 68.0 mol% and Q-10 was the major detected isoprenoid quinone. The polar lipids were three unidentified phospholipids, three unidentified glycolipids, and two unidentified lipids. The dominant fatty acids were anteiso-C15:0, C16:0, anteiso-C17:0 and C18:0Citromicrobium-and polyphasic taxonomic analyses, strain CBA4602T represents a novel genus and species. The name Citrimicrobium luteum is proposed for the type strain CBA4602T (=KACC 17668T =JCM 19530T)." />
