Strain GSS12(T), a Gram-negative, aerobic, non-flagellated, ovoid- to rod-shaped (0.5-0.7 x 0.9-3.0 A mu m) bacterium, was isolated from Yuncheng Saline Lake, China. Growth occurred with 0.5-16.0 % (w/v) NaCl (optimum 4.5 %), at pH 5.0-10.0 (optimum pH 6.0-6.5) and at 10-50 A degrees C (optimum 37 A degrees C). The major fatty acids (> 5.0 %) found in GSS12(T) were summed feature 8 (72.2 %), C-16:0 (9.0 %) and C-18:1 omega 7c 11-methyl (6.4 %). The DNA G+C content was 62.7 mol%. Analysis of the 16S rRNA gene sequences showed that strain GSS12(T) forms a stable clade with species of the genus R...
