sp. nov., a slightly thermophilic bacterium isolated from a hot spring Free

Abstract

A slightly thermophilic, aerobic bacterium, designated YIM 72257, was isolated from a sediment sample taken from a hot spring in Tengchong county, Yunnan province, south-west China. The isolate was Gram-stain-negative, non-sporulating and forms non-motile rods, appearing in chains. The isolate grew at 50–65 °C, pH 6.0–9.0 and with 0.5–1 % NaCl (w/v). 16S rRNA gene sequence analysis showed that strain YIM 72257 was most closely related to LY1 (95.6 %), DSM 1279 (95.1 %) and WR-30 (94.6 %). The genomic DNA G+C content of strain YIM 72257 was 62.6 mol%. The main cellular fatty acids (>5 %) were anteiso-C, anteiso-C, iso-C, iso-C, iso-C and C. The polar lipids consisted of an uncharacterized phospholipid and two glycolipids. Based on phenotypic, phylogenetic and chemotaxonomic characteristics, strain YIM 72257 is proposed to be a representative of a novel species of the genus , for which the name sp. nov. is proposed. The type strain is YIM 72257 (=KCTC 52599=CCTCC AB 2017100).
