Abstract:
A Gram-stain-negative, aerobic, heterotrophic and salt-tolerant bacterium, designated strain LL-001T, was isolated from a deep subseafloor sediment in Japanese waters. Cells were non-motile rods and colonies were smooth, convex, circular and vermilion. The conditions for growth were 15–35 °C, pH 5.5–7.5 and 1–8 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences confirmed that strain LL-001T belonged to the genus Loktanella within the family Rhodobacteraceae of the class Alphaproteobacteria. 16S rRNA gene sequence similarity between strain LL-001T and members of the genus Loktanella was 94.5–98.5 %; the highest sequence similarity was with Loktanella hongkongensis UST950701-009PT. DNA–DNA relatedness between strain LL-001T and L. hongkongensis UST950701-009PT was 41.5–43.6 %. The DNA G+C content of strain LL-001T was 69.3 mol%. On the basis of biochemical features and 16S rRNA gene sequence comparison, strain LL-001T is considered to represent a novel species of the genus Loktanella, for which the name Loktanella cinnabarina sp. nov. is proposed. The type strain is LL-001T ( = JCM 18161T = CECT 8072T). The description of the genus Loktanella is also emended.
