An aerobic bacterium, designated strain Dysh456T, was isolated from a crude oil-contaminated soil. Cells of strain Dysh456T were rod-shaped, motile, and Gram-stain-negative. Strain Dysh456T grew at 13-48 °C and pH 4.3-7.9. Major cellular fatty acids were iso-C15:0 (42.5%), iso-C17:0 (15.3%) and summed feature 9 (iso-C17:1 ω9c/C16:0 10-methyl [13.7%]). Major respiratory quinone was ubiquinone-8. The genome of strain Dysh456T consists of a single circular chromosome of 2,874,969 bp in length with G + C content of 68.3%. Phylogenetic analysis based on the 16S rRNA gene sequences indicated that strain Dysh456T belongs to the family Rhodanobacteraceae, but none of the existing genera can accommodate this novel isolate. On the basis of physiological, chemotaxonomic, and genomic properties, strain Dysh456T (= NBRC 112897T = DSM 105662T) is proposed as the type strain representing a novel species of novel genus, for which the name Aerosticca soli gen. nov., sp. nov. is proposed.

Keywords: Gammaproteobacteria; Moderate thermophile; Novel genus; Oilfield soil; Rhodanobacteraceae; Thermotolerance.
