タイトル Four novel Arthrobacter species isolated from filtration substrate.
ジャーナル Int J Syst Evol Microbiol
Abstract Four Gram-positive, non-motile, non-spore-forming bacterial strains, LC4(T), LC6(T), LC10(T) and LC13(T), were isolated from a filtration substrate made from trass, a volcanic rock, and their taxonomic positions were investigated by a polyphasic taxonomic approach. The novel strains grew over a temperature range of 5-40 degrees C, at pH values of 6-11 and in the presence of 3-7 % (w/v) NaCl. A phylogenetic tree based on 16S rRNA gene sequences showed the novel strains formed a distinct evolutionary lineage within the genus Arthrobacter. Chemotaxonomic analyses demonstrated that the major menaquinone was MK-9(H(2)), a menaquinone typical of the Arthrobacter globiformis group. The major fatty acid was anteiso-C(15 : 0) and the major amino acid present in the cell-wall peptidoglycan was l-lysine. These observations supported the affiliation of the novel strains to the genus Arthrobacter. On the basis of their morphological, physiological and genotypic characteristics, the new isolates are considered to represent four novel species of the genus Arthrobacter, for which the names Arthrobacter niigatensis sp. nov. (type strain LC4(T)=IAM 15382(T)=CCTCC AB 206012(T)), Arthrobacter alkaliphilus sp. nov. (type strain LC6(T)=IAM 15383(T)=CCTCC AB 206013(T)), Arthrobacter echigonensis sp. nov. (type strain LC10(T)=IAM 15385(T)=CCTCC AB 206017(T)) and Arthrobacter albidus sp. nov. (type strain LC13(T)=IAM 15386(T)=CCTCC AB 206018(T)) are proposed.
