Abstract
A non-spore-forming, Gram-stain-positive, short rod-shaped strain, designated SJQ22T, was isolated from a paddy soil sample collected in Shanghai, PR China. A comparative analysis of 16S rRNA gene sequences showed that strain SJQ22T fell within the genus Aerococcus , forming a clear cluster with the type strains of Aerococcus viridans (98.6 % sequence similarity) and Aerococcus urinaeequi (98.5 % sequence similarity). Strain SJQ22T grew at 30–45 °C (optimum, 30 °C), pH 6.0–8.0 (optimum, pH 7.0) and with a NaCl concentration of 0–4 % (optimum, 1 %). Cells were negative for oxidase and catalase activity. Chemotaxonomic analysis showed that strain SJQ22T possessed C16:0 and C18:1 ω9c as the predominant fatty acids. The DNA G + C content was 39.0 mol%. Strain SJQ22T exhibited DNA–DNA relatedness levels of 13±2 % with A. viridans ATCC 11563T and 9±2 % with A. urinaeequi IFO 12173T. Based on the data obtained, strain SJQ22T represents a novel species of the genus Aerococcus , for which the name Aerococcus agrisoli sp. nov. is proposed. The type strain is SJQ22T (=JCM 33111T=CCTCC AB 2018283T).
