The Arthrobacter genus is commonly found amongst soil bacteria. Species that are members of this genus are gram positive, obligate aerobes. They are chemoorganotrophs and have an oxidative metabolism (Holt et al., 1994). Arthrobacter species have been particularly useful in the bioremediation of groundwater contaminated with pesticides and herbicides; this is made possible because of their adaptable genomes, which can handle stressful conditions and environments. (Mongodin et al., 2006).
