		Arthrobacter species are found in extreme environments, such as the arctic sea, under leaking radioactive waste tanks, and in distilled water.
		Arthrobacter strains are metabolically diverse, and are capable of catabolizing a variety of xenobiotic compounds, including glyphosate, methyl tert-butyl ether, 2,4-dichlorophenoxyacetate (2,4-D), nictotine, 4-nitrophenol, dimethylsilanediol, fluorene, phthalate, nitroglycerine and diverse s-triazine compounds.
		Due to their metabolic diversity, Arthrobacter species have been used in industrial applications and are currently being used in the bioremediation of contaminated groundwater.

	Arthrobacter - Wikipedia, the free encyclopedia
		Arthrobacter is a genus of bacteria that is commonly found in soil.
		Colonies of Arthrobacter have a greenish metallic center on mineral salts pyridone broth incubated at 20°C.
		This genus is distinctive because of its unusual habit of "snapping division" in which the outer cell wall ruptures at a joint (hence its name).

	Proceedings of the Oklahoma Academy of Science
		Growth of Arthrobacter crystallopoietes in complex media is accompanied by distinct morphological changes that occur in an exclusively vegetative life cycle.
		Arthrobacter crystallopoietes (ATCC 1581) was grown in a medium containing (w/v) yeast extract (0.25%), tryptone (0.5%), and glucose (0.1%) at a pH of 7.0.
		Like the specific activity, the methylating capacity of the crude extracts appears to decrease during the transition from coccoid to rod morphology, which together suggest that specific classes of methylases are changing independently.

	Bacterial Sedimentation (Site not responding. Last check: 2007-11-05)
		The two, nonmotile bacterial strains selected for sedimentation experiments were Arthrobacter globiformis B672 (isolated from the Middendorf aquifer, 259-m depth), and OYS3, a streptomycin-resistant strain isolated from shallow groundwaters at Oyster, Virginia (U.S.A.).
		The Arthrobacter B672 and OYS3 strains sedimented through saturated sand columns (quartz sand, 300 to 420 mm diameter) under hydrostatic conditions at median velocities of 7 and 17 mm day-1.
		Thus, the sedimentation model is consistent with sand column observations on Arthrobacter B672, and too simplistic in the case of OYS3.

	Manganese Oxidation by Pseudomonas putida
		"Arthrobacter siderocapsulatus" is the species defined to include two manganese-oxidizing isolates which were claimed to be members of the previously uncultured Siderocapsa group.
		These two strains were assigned to the genus Arthrobacter solely on the basis of the observation that in young cultures, cells appeared as short rods or long filaments, while in older cultures, a mixture of short rods and cocci were present.
		Arthrobacter globiformis, mentioned by Dubinina and Zhdanov (1975) to oxidize manganese, was the only one of these other strains to form brown colonies on the media I tested, and the type strain (ATCC 8010) did so only at very low frequency.

		We describe here the properties of a second isolate, Arthrobacter strain VAI-A, obtained from the same enrichment culture that yielded V. paradoxus VAI-C. Although strain VAI-A grew rapidly and exponentially on a number of substrates, it grew only slowly and aberrantly (i.e., linearly) in media amended with oxohexanoyl-HSL as the sole energy source.
		This suggested that the original coenrichment of these two organisms from the same soil sample was not coincidental and that consortia may play a role in quorum signal turnover and mineralization.
		The fact that Arthrobacter strain VAI-A utilizes the two known nitrogenous degradation products of acyl-HSLs, acyl-homoserine and HSL, begins to explain why none of the three compounds are known to accumulate in the environment.
