Arthrobacter globiformis

Arthrobacter globiformis was first discovered by H. J. Conn in 1928. This bacteria was initially found in large quantities in various types of soil.{{Cite book |last=Conn |first=H. J. |url=https://books.google.com/books?id=dRgIcgAACAAJ |title=A Type of Bacteria Abundant in Productive Soils, But Apparently Lacking in Certain Soils of Low Productivity |date=1928 |publisher=Cornell University |language=en}} They start as Gram-negative rods before becoming Gram-positive cocci over time. They may also become large, oval-shaped cells called cystite by growing them in very high carbon to nitrogen ratio environments.{{Cite journal |last1=Duxbury |first1=T. |last2=Gray |first2=T. R.

They may also have flagella as well.{{Cite journal |last1=García-López |first1=María-Luisa |title=Micrococcus |date=1999-01-01 |url=https://www.sciencedirect.com/science/article/pii/B0122270703010254 |journal=Encyclopedia of Food Microbiology |pages=1344–1350 |editor-last=Robinson |editor-first=Richard K. |place=Oxford |publisher=Elsevier |language=en |isbn=978-0-12-227070-3 |access-date=2022-03-15 |last2=Santos |first2=Jesús-Ángel |last3=Otero |first3=Andrés}} Notably, A. globiformis and its antigens and proteins are commercially available for use in research, food production, biodegradation, and water/wastewater treatment.{{Cite web |last= |first= |date=2018-02-23 |title=Arthrobacter globiformis - information sheet |url=https://www.canada.ca/en/health-canada/services/chemical-substances/fact-sheets/chemicals-glance/arthrobacter-globiformis.html |access-date=2022-03-15 |website=Health Canada}}

A. globiformis can break down substances in the soil such as agricultural chemicals, chromium, etc. They are primarily aerobic, but they can survive anaerobically using lactate, acetate, and ethanol producing fermentation for growth. Most are heterotrophic, meaning they cannot produce their own food. The choline oxidase activity of A. globiformis has been extensively characterized and is important for the production of glycine betaine, one of the few soluble osmotic regulators used by most cells.{{Cite journal |last=Gadda |first=Giovanni |title=Chapter Six - Choline oxidases |date=2020-01-01 |url=https://www.sciencedirect.com/science/article/pii/S187460472030007X |journal=The Enzymes |volume=47 |pages=137–166 |editor1-last=Chaiyen |editor1-first=Pimchai |series=Flavin-Dependent Enzymes: Mechanisms, Structures and Applications |publisher=Academic Press |doi=10.1016/bs.enz.2020.05.004 |pmid=32951822 |s2cid=221826501 |language=en |access-date=2022-03-15 |editor2-last=Tamanoi |editor2-first=Fuyuhiko|url-access=subscription }}

The complete genome of A. globiformis has been sequenced using whole-genome shotgun sequencing. The genomes of three strains are available for public use.{{Cite web |title=Arthrobacter globiformis (ID 12154) |url=https://www.ncbi.nlm.nih.gov/genome/12154 |access-date=2022-03-15 |website=NCBI Genome}} The genome is approximately 4.89 million base pairs long, containing 4305 proteins and a 66.1% GC content. Two major phylogenetic clades exist within the Arthrobacter genus, the A. globiformis/A. citreus group and the A. nicotianae group.{{Cite web |title=Home - Arthrobacter sp. FB24 |url=https://genome.jgi.doe.gov/portal/art_f/art_f.home.html |access-date=2022-03-15 |website=Joint Genome Institute}} These two clades differ mainly in their peptidoglycan structure, teichoic acid content, and lipid composition.
