Abstract A Gram-positive and aerobic actinobacterium, strain SYSU D 8006T, was isolated from a desert sand sample collected from Gurbantunggut desert, China. Phenotypically, the strain was found to grow at 14–50 °C, pH 6.0–9.0 and in the presence of up to 4% (w/v) NaCl. The chemotaxonomic features of strain SYSU D 8006T included menaquinone MK-9(H4) as the respiratory quinone, diphosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine, phosphatidylinositol and phosphatidylinositol mannoside as known polar lipids, iso-C15:0, iso-C16:0, C17:1 ω8c and C 18:1 ω9c as the predominant fatty acids, and arabinose, galactose and glucose as the whole cell sugars. Strain SYSU D8006T shared the highest 16S rRNA gene sequence identity with Blastococcus jejuensis DSM 19597T (98.2%). Based on the analyses of the phenotypic, genotypic and phylogenetic characteristics, strain SYSU D 8006T is characterized to represent a novel species of the genus Blastococcus, for which the name Blastococcus deserti sp. nov. is proposed. The type strain is SYSU D 8006T (= CGMCC 1.15935T = KCTC T T 49026 = CPCC 204618 ). Keywords Blastococcus deserti sp. nov. · Xinjiang · Gurbantunggut Desert

During a survey for method and means for culturing previously uncultivated actinobacteria, we have collected samples from deserts located in Saudi Arabia and Gurbantunggut desert, China and inoculated the sample in diluted defined isolation media (Yang et al. 2017; Asem et al. 2018). Among many of the putative novel taxa isolated from these samples, one strain showed high 16S rRNA sequence identity to members of the genus Blastococcus. This study described the characterization of the strain as a member of the genus Blastococcus
