title: Falsirhodobacter deserti sp. nov., isolated from sandy soil.
abstract: A Gram-stain-negative, non-motile, heterotrophic, rod-shaped bacterium, designated strain W402(T), was isolated from an enrichment culture of a Tamarix ramosissima rhizosphere soil sample from the Xinjiang desert in the PR China. Analysis of the almost-complete 16S rRNA gene sequence showed that the isolate was phylogenetically related to a species of the genus Falsirhodobacter, having a close relationship to Falsirhodobacter halotolerans JA744(T) (97 % similarity). However, DNA-DNA relatedness between W402(T) and F. halotolerans JA744(T) was 43.2±1.2 %. Strain W402(T) grew in 0-10 % (w/v) NaCl. The temperature and pH ranges for growth were 10-40 °C and pH 5.5-10.0, respectively. Optimal growth occurred at 1-3 % (w/v) NaCl, 30 °C and pH 7.0. The predominant cellular fatty acids were summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c, 61.4 %), C18 : 0 (9.8 %) and 11-methyl C18 : 1ω7c (8.2 %). The major quinone of strain W402(T) was Q-10. Phosphatidylethanolamine was predominant in the polar lipid profile. The DNA G+C content of strain W402(T) was 67.3 mol%. Taken together, these results confirm that W402(T) represents a novel species of the genus Falsirhodobacter, for which the name Falsirhodobacter deserti sp. nov. is proposed. The type strain is W402(T) ( = ACCC 05851(T) = KCTC 32408(T)).
