Fernanda A1 da Costa, Milton S.YR 2011 T1 Schleiferia thermophila gen. nov., sp. nov., a slightly thermophilic bacterium of the phylum ‘Bacteroidetes’ and the proposal of Schleiferiaceae fam. nov. JF International Journal of Systematic and Evolutionary Microbiology, VO 61 IS 10 SP 2450 OP 2455 DO https://doi.org/10.1099/ijs.0.028852-0 PB Microbiology Society, SN 1466-5034, AB A bacterial isolate, with an optimum growth temperature of about 50 °C and an optimum pH for growth between 7.5 and 8.5, was recovered from a hot spring in the Furnas area of the Island of São Miguel in the Azores. The novel isolate is orange-pigmented, forms non-motile, rod-shaped cells that stain Gram-negative, is strictly aerobic, oxidase-positive and catalase-negative. The major fatty acids of strain TU-20T are 16 : 1ω6c, 17 : 0 iso 3-OH and 15 : 0 iso. Menaquinone 6 is the major respiratory quinone. Based on 16S rRNA gene sequence analysis, physiological and biochemical characteristics, we describe a novel species of a novel genus represented by strain TU-20T ( = DSM 21410T  = LMG 24594T) for which we propose the name Schleiferia thermophila gen nov., sp. nov. We also propose the family Schleiferiaceae fam. nov. to accommodate this new genus., UL https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.028852-0
