Project description:We announce a 4.63-Mb genome assembly of an isolated bacterium that is the first sequenced nicotine-degrading Arthrobacter strain. Nicotine catabolism genes of the nicotine-degrading plasmid pAO1 were predicted, but plasmid function genes were not found. These results will help to better illustrate the molecular mechanism of nicotine degradation by Arthrobacter.
Project description:Arthrobacter sp. strain FB24 is a species in the genus Arthrobacter Conn and Dimmick 1947, in the family Micrococcaceae and class Actinobacteria. A number of Arthrobacter genome sequences have been completed because of their important role in soil, especially bioremediation. This isolate is of special interest because it is tolerant to multiple metals and it is extremely resistant to elevated concentrations of chromate. The genome consists of a 4,698,945 bp circular chromosome and three plasmids (96,488, 115,507, and 159,536 bp, a total of 5,070,478 bp), coding 4,536 proteins of which 1,257 are without known function. This genome was sequenced as part of the DOE Joint Genome Institute Program.
Project description:We report the draft genome sequence of Arthrobacter sp. strain Edens01, isolated from a leaf surface of a Rosa hybrid plant as part of the Howard Hughes Medical Institute-funded Student Initiated Microbial Discovery (SIMD) project. The genome has a total size of 3,639,179 bp and contig N50 of 454,897 bp.
Project description:Here, we report the draft genome sequence of Arthrobacter sp. strain ATCC 49987, consisting of three contigs with a total length of 4.4 Mbp. Based on the genome sequence, we suggest reclassification of Arthrobacter sp. strain ATCC 49987 as Pseudarthrobacter sp. strain ATCC 49987.
Project description:Arthrobacter sp. strain PAO19 is a polyphosphate-accumulating organism isolated from maize rhizosphere soil. Here we report its genome sequence, which may shed light on its role in phosphate removal from water bodies. To our knowledge, this is the first genome announcement of a polyphosphate-accumulating strain of the genus Arthrobacter.
Project description:Five Arthrobacter isolates from clinical specimens were studied by phenotypic, chemotaxonomic, and genetic characterization. Two strains had characteristics consistent with those of Arthrobacter oxydans. One strain was related to A. citreus; however, DNA-DNA hybridization and phenotypic characteristics indicated that this strain belongs to a new species, for which the name Arthrobacter luteolus sp. nov. is proposed. Two strains were closely related to A. cumminsii by 16S rRNA gene sequencing, but DNA-DNA hybridization, peptidoglycan type, and some phenotypic features indicated that they should be assigned to a new species, for which the name Arthrobacter albus sp. nov. is proposed. The type strain of A. luteolus is CF25 (DSM 13067). The type strain of A. albus is CF43 (DSM 13068).
Project description:A novel desiccation-tolerant, xeroprotectant-producing bacterium, designated strain 4J27(T), was isolated from a Nerium oleander rhizosphere subjected to seasonal drought in Granada, Spain. Phylogenetic analysis based on 16S rRNA gene sequencing placed the isolate within the genus Arthrobacter, its closest relative being Arthrobacter phenanthrenivorans Shep3 DSM 18606(T), with which it showed 99.23?% 16S rRNA gene sequence similarity. DNA-DNA hybridization measurements showed less than 25?% relatedness between strain 4J27(T) and Arthrobacter phenanthrenivorans DSM 18606(T). The DNA base composition of strain 4J27(T) was 65.3 mol%. The main fatty acids were anteiso C15?:?0, anteiso C17?:?0, C16?:?0 and iso C16?:?0 and the major menaquinone was MK-9 (H2). The peptidoglycan type was A3? with an l-Lys-l-Ser-l-Thr-l-Ala interpeptide bridge. The bacterium tested positive for catalase activity and negative for oxidase activity. Phylogenetic, chemotaxonomic and phenotypic analyses indicated that the desiccation-tolerant strain 4J27(T) represents a novel species within the genus Arthrobacter, for which the name Arthrobacter siccitolerans is proposed. The type strain is 4J27(T) (?=?CECT 8257(T)?=?LMG 27359(T)).
Project description:Arthrobacter sp. B6 is a Gram-positive, non-motile, facultative aerobic bacterium, isolated from the arsenic-contaminated aquifer sediment in the Datong basin, China. This strain displays high resistance to arsenic, and can dynamically transform arsenic under aerobic condition. Here, we described the high quality draft genome sequence, annotations and the features of Arthrobacter sp. B6. The G?+?C content of the genome is 64.67%. This strain has a genome size of 4,663,437 bp; the genome is arranged in 8 scaffolds that contain 25 contigs. From the sequences, 3956 protein-coding genes, 264 pseudo genes and 89 tRNA/rRNA-encoding genes were identified. The genome analysis of this strain helps to better understand the mechanism by which the microbe efficiently tolerates arsenic in the arsenic-contaminated environment.
