Abstract:
A Gram-negative, aerobic, short rod-shaped, non-motile, pale-yellow bacterial strain was isolated from biological soil crusts collected in the desert of Kubuqi, Inner Mongolia of China, designated MIMBbqt12T. The G+C content of the genomic DNA of strain MIMBbqt12T was 49.5 mol%. Phylogenetic analysis using 16S rRNA gene sequences showed that strain MIMBbqt12T belongs to the genus Spirosoma with the highest sequence similarity of 93.5 % to Spirosoma arcticum R2-35T. The major fatty acids of strain MIMBbqt12T were C16 : 0, iso-C15 : 0, iso-C17 : 03-OH, C16 : 1ω5c and summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c). The results of phenotypic properties and phylogenetic distinctiveness supported that strain MIMBbqt12T represents a novel species of the genus Spirosoma, for which the name Spirosoma soli sp. nov. is proposed. The type strain is MIMBbqt12T (=MCCC 1K01308T=KCTC 42805T).
