sp.nov., a plant growth promoting bacteria for agriculture in water-scarce conditions isolated from rhizosphere.

A gram-positive, nonpathogenic, central endospore-forming, flagellated strain, was successfully isolated from the rhizosphere of in Aracena (Spain). Its optimal growth conditions are 28 °C, pH 6, and 0 % salinity. It is able to assimilate glucose, L-fucose, L-arabinose, b-metil-D-xylose and shows high catabolic capacity. The major fatty acids (>79.20 % of the total fatty acids) are anteiso C15:0 > iso C15:0 > C14:0. A phylogenetic analysis based on the 16S rRNA gene sequence revealed similarity to DSM8801 (99.9 %), CECT30509 (99.8 %), and DSM1321 (99.6 %). Comparison of whole genomes revealed that strain BBB004 is more similar to DSM1321. According to ANI (93.54 %), AAI (94 %), dDDH (60.6), %G + C (0.12), TETRA (0.99822) and intergenomic distance (0.2835) values, therefore this species is different to the closest. A total of 133 genes unique to BBB004 were identified. Supported by these analyses, strain BBB004 (=LMG32742 = CCUG76477) was proposed as the type strain for a new species, named " sp. nov."
