Abstract
Three psychrotrophic Arthrobacter strains, isolated from Antarctic lake sediment (An24, An25T) 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 degrees C and 30 degrees C, with optimal growth temperature around 25 degrees C. The cell wall peptidoglycan was A4alpha 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 An25T (CGMCC 1.3685, JCM 12921) was proposed.Entities:
