| Abstract |
A Gram-stain-negative, non-motile and golden-yellow pigmented bacterium, designated strain YJPT1-3T, was isolated from a tidal flat sediment collected in Yongyu-do, Republic of Korea. The strain grew optimally at 30 °C, pH 7.0, and with 2% (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences placed strain YJPT1-3T within the family Flavobacteriaceae, with the closest relatives being Arenibacter nanhaiticus NH36AT (90.3%), Sediminicola luteus CNI-3T (90.2%), Muriicola soli MMS17-SY002T (90.0%), C. algicola DSM 14237T (90.0%) and Eudoraea chungangensis CAU 1296T (89.9%). Comparative genome analyses with closely related species revealed that strain YJPT1-3T exhibited average nucleotide identity analysis values ranging from 67.1% to 67.9% and digital DNA-DNA hybridization values between 24.8% and 31.0%. The genome of strain YJPT1-3T consisted of a single circular contig of 3.16 Mb with a G+C content of 45.8 mol%. The predominant cellular fatty acids were C15 : 0 iso (18.8%), C15 : 1 iso G (15.4%) and SF3 (C16 : 1 ω6c and/or C16 : 1 ω7c, 11.0%), while the major respiratory quinone was MK-6. The polar lipid profile included phosphatidylethanolamine, aminolipids, polar lipids and four unidentified lipids. Based on phenotypic, phylogenetic, genomic and chemotaxonomic characteristics, strain YJPT1-3T represents a novel genus within the family Flavobacteriaceae, for which the name Croceiramulus getboli gen. nov., sp. nov. is proposed. The type strain is YJPT1-3T (=KCTC 102028T=KACC 23272T=JCM 36479T).
