Arthrobacter
Sign in to saveArthrobacter (from the Greek, "jointed small stick”) is a genus of bacteria that is commonly found in soil. Members of the genus have also been reported from insect-associated environments, suggesting ecological roles beyond soil habitats. All species in this genus are Gram-positive obligate aerobes that are rods during exponential growth and cocci in their stationary phase. Arthrobacter have a distinctive method of cell division called "snapping division" or reversion in which the outer bacterial cell wall ruptures at a joint.

Members of the genus have also been reported from insect-associated environments, suggesting ecological roles beyond soil habitats.

==Description== Arthrobacter can be grown on mineral salts pyridone broth, where colonies have a greenish metallic center on incubated at . Under the microscope, Arthrobacter appear as rods when rapidly dividing, and cocci when in stationary phase. Dividing cells may also appear as chevrons ("V" shapes). Other notable characteristics are that it can use pyridone as its sole carbon source, and that its cocci are resistant to desiccation and starvation.
