Description of high-altitude, cold-adaptive, metabolically versatile <i>Dyadobacter aurulentus</i> sp. nov. isolated from Western Himalayan farmland soils.

ABSTRACT: A novel bacterial strain, designated UC10^T, was isolated from cold, high-altitude farmland soil in the Gangotri region of the Western Himalayas, India. The strain is Gram-stain-negative, aerobic, non-spore forming, and non-motile, forming golden colonies that produce a flexirubin-like pigment. Strain UC10^T grows over a broad range of temperatures (5°C-30°C), pH (6-11), and salinities (up to 4% NaCl), with optimal growth at 30°C, pH 7.0, and 1% NaCl. The nearly full-length 16S rRNA gene sequence (MK743979) shares 98.95% similarity with Dyadobacter luticola, followed by 97.68% with Dyadobacter crusticola and 97.40% with Dyadobacter koreensis, and phylogenetic analysis places UC10ᵀ in a distinct clade within the genus Dyadobacter.
