Abstract
The novel strain AM35T was isolated from the faeces of C57BL/6 mice. These cells are strictly anaerobic, gram negative, oxidase negative, catalase positive, rod-shaped and non-motile. The strain produced creamy yellowish colonies on brain heart infusion (BHI) agar with hemin. Growth was investigated at 30-41 °C in the presence of 0.5-1.5% (w/v) NaCl at pH 6.5-8.5. Taxonomic analysis based on 16S rRNA gene sequencing revealed that strain AM35T is affiliated with the family Muribaculaceae and closely related to the genus Muribaculum. The genomic DNA G + C content of strain AM35T was 47.8 mol%. We detected the whole-cell sugars ribose and galactose; meso-2,6-diaminopimelic acid was absent. The major fatty acids (> 10%) were anteiso-C15:0 and iso-C15:0; the major polar lipid was phosphatidylethanolamine. The major respiratory quinones were MK-10 and MK-11. Based on our phylogenetic, phenotypic and chemotaxonomic analyses, strain AM35T represents a novel genus within the family Muribaculaceae, for which we propose the name Heminiphilus faecis gen. nov., sp. nov. The type strain of Heminiphilus faecis gen. nov., sp. nov. is AM35T (= KCTC 15907 T = DSM 110151 T).
