Acknowledgements We thank Prof L. G. Sun for providing the Antarctic lake sediments. Thanks also given to the crews of the Da Yang No. 1 for help in collecting the deep-sea samples. Thanks to Prof. D.H. Bartlett for suggestions in high-pressure cultivation. This work was supported in part by the Chinese High Tech (863) program (2004AA621010) and specific funding for preliminary fundamental research (202CCA05000) and COMRA Fund (DY105-04-02).

N2 - Three psychrotrophic Arthrobacter strains, isolated from Antarctic lake sediment (An24, An25 T ) and deep-sea sediment (ZX6) were studied. Their 16S rRNA gene sequences showed highest similarities (97.0-97.9%) with those of A. nicotianae and A. protophormiae. All three strains underwent rod-coccus morphological change, had high mol% G+C content, were aerobic to slightly anaerobic, and grew between 0°C and 30°C, with optimal growth temperature around 25°C. The cell wall peptidoglycan was A4α variant. DNA-DNA hybridization, physiological and chemotaxonomic studies indicated that these three strains constituted a new homogeneous genomic species within the genus Arthrobacter, for which the name Arthrobacter ardleyensis, with the type strain An25 T (CGMCC 1.3685, JCM 12921) was proposed.
