Six isolates were recovered from great scallop (Pecten maximus) broodstock in a hatchery in Bergen, Norway. The strains were thoroughly characterized by a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences indicated that these strains are related to the genus Sinobacterium, showing sequence similarities between 96.97 and 97.63 % with the only species of the genus, Sinobacterium caligoides. Phenotypic characterization showed that the strains are typical marine halophiles, Gram negative, aerobic chemoorganotrophs, and allowed their differentiation from the closely related taxa. The G+C content of the novel strains was 52.2 ± 1 mol% and the predominant fatty acids were C₁₆:₀, C₁₆:₁ ω₇c/C₁₆:₁ ω₆c and C₁₈:₁ ω₇c. The value for DNA–DNA relatedness between strain 3CM4ᵀ and the S. caligoides type strain LMG 25705ᵀ was 46 %. Hybridization values between strain 3CM4ᵀ and the other scallop isolates ranged from 82 to 93.6 %. Based on all data collected, the six scallop strains represent a novel species of the genus Sinobacterium, for which the name Sinobacterium norvegicum sp. nov., is proposed with strain 3CM4ᵀ (=CECT 8267ᵀ; =CAIM 1884ᵀ) as type strain.
