| Abstract |
A Gram-stain-negative, non-motile, rod-shaped, aerobic bacterium, designated HYT19T, was isolated from soil of Mountain Danxia in southern China. It showed the highest similarity of 16S rRNA gene sequence (97.0%) and formed a monophyletic clade with Fibrisoma limi BUZ 3T. Strain HYT19T grew at 16-37 °C (optimum 28-30 °C) and at pH 6-7. The draft genome size of strain HYT19T was 7.8 Mb with a DNA G+C content of 54.0 mol%. The digital DDH and average nucleotide identity values between strain HYT19T and F. limi BUZ 3T were 28.8% and 85.1%, respectively. MK-7 was the sole respiratory quinone. The major polar lipids were phosphatidylethanolamine, unidentified aminophospholipid, two unidentified aminolipids, unidentified phospholipid and unidentified lipid. The strain contained C16:1ω5c, iso-C15:0, summed feature 3 (C16:1ω6c and/or C16:1ω7c), C16:0, iso-C17:0 3-OH and anteiso-C15:0 as the major fatty acids. On the basis of phylogenetic, genomic, phenotypic and chemotaxonomic analysis, we propose a new species Fibrisoma montanum sp. nov. of genus Fibrisoma. The type strain is HYT19T (= CCTCC AB 2018342T = JCM 33105T).
