title: Gelidibacter sediminis sp. nov., isolated from a sediment sample of the Yellow Sea.
abstract: The Gram-stain-negative, yellow-pigmented, rod-shaped bacterial strain, designated S11-41(T), was isolated from a sediment sample of the Yellow Sea in China. The strain was able to grow well over a wide temperature range (1-35 °C). Phylogenetic analysis based on 16S rRNA gene sequences showed that strain S11-41(T) was related to the members of the genus Gelidibacter, sharing highest sequence similarities with the type strains of Geldibacter salicanalis (98.2%), Geldibacter algens (97.4%) and Geldibacter mesophilus (96.9%). The genomic DNA G+C content of strain S11-41(T) was 39.2 mol%. The predominant cellular fatty acids were iso-C15 : 0 (13.2%), iso-C17 : 0 3-OH (12.8%) and iso-C15 : 1 G (12.2%). Phosphatidylethanolamine was identified as the major polar lipid. Combined data from phenotypic, phylogenetic and DNA-DNA relatedness studies demonstrated that strain S11-41(T) is a representative of a novel species of the genus Gelidibacter, for which we propose the name Gelidibacter sediminis sp. nov. (type strain S11-41(T)= DSM 28135(T) = LMG 28076(T)).
