| contents | Description of gen. nov., a novel genus within the family, and its type species sp. nov., isolated from marine sponges. Oliveira, Vanessa Ferreira, Inês Cleary, Daniel F R Huang, Yusheng M Costa, Rodrigo Keller-Costa, Tina Gomes, Newton C M Phylogeny Animals Fatty Acids RNA, Ribosomal, 16S Base Composition Taiwan Bacterial Typing Techniques DNA, Bacterial Ubiquinone Sequence Analysis, DNA Porifera Marine sponges host diverse microbial communities that play essential roles in nutrient cycling and host health. During a study of the microbiota of marine sponges from Taiwan, two Gram-stain-negative, motile and facultatively anaerobic strains, XeTr1 and StTr2, were isolated from sp. and , respectively. Cells were rod-shaped and showed catalase and oxidase activities. Growth was observed at 15-37 °C, pH 6.0-9.0 and 1.0-3.0% (w/v) NaCl. Strains XeTr1 and StTr2 contained ubiquinone-8 and ubiquinone-9 as major quinones and summed feature 3 (C ), summed features 8 (C ) and C as major fatty acids. The major polar lipids identified in strains XeTr1 and StTr2 were phosphatidylethanolamine and phosphatidylglycerol. Phylogenetic analysis based on the 16S rRNA gene sequence placed strains XeTr1 and StTr2 within the family , forming a distinct lineage that shared 94% or less sequence homology with its closest relatives, including NE40, CBAS 572 and CL-33. The average amino acid identity values were below the cutoff range for species of the same genus, supporting the placement of strains XeTr1 and StTr2 as representing a novel genus within the family . Distinct phenotypic and chemotaxonomic characteristics, combined with low sequence similarity and a clear phylogenetic separation from known genera, support the proposal of a novel genus and species in the family , for which the name gen. nov., sp. nov. is proposed. The type strain is XeTr1 (=JCM 37577=UCCCB 249). |
