sp. nov., isolated from Kubuqi Desert soil.

A Gram-stain positive, facultatively anaerobic, motile rod-shaped strain, BY-33, was isolated from a soil sample obtained from the Kubuqi Desert, PR China. Phylogenetic analysis based on 16S rRNA gene sequence similarity revealed that strain BY-33 was most closely related to the genus , including CF5-4 (98.2 % similarity), '' HO-Ch2 (98.

sp. nov., isolated from desert soil.

A Gram-stain-positive, facultative anaerobic, motile and rod-shaped bacterial strain, DG-18, was isolated from desert soil sampled at the Kubuqi Desert in Inner Mongolia, China. Strain DG-18 grew at 4-40 °C (optimum, 25-30 °C), at pH 8.0-10.

sp. nov., isolated from Antarctic soil.

Strain 3F2 was isolated from a soil sample obtained from the surface of Deception Island, Antarctica. The isolate was a Gram-stain-negative, aerobic, non-motile, rod-shaped bacterium, and its colonies were red to pink in colour. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain 3F2 belonged to the genus , family and was most closely related to DG5B (97.
