Arthrobacter Mobilis
''Arthrobacter'' (from the Greek, "jointed small stick”) is a genus of bacterium, bacteria that is commonly found in soil. All species in this genus are Gram-positive obligate aerobes that are bacterial shape, rods during exponential growth and bacterial shape, cocci in their Stationary phase (biology), stationary phase. ''Arthrobacter'' have a distinctive method of cell division called "snapping division" or reversion (microbiology), reversion in which the outer bacterial cell wall ruptures at a joint. 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. Use in industry ''Arth ...

Arthrobacter Globiformis
''Arthrobacter globiformis'' is a gram-positive bacterium species from the genus of ''Arthrobacter''. Description and Significance ''Arthrobacter globiformis'' was first discovered by H. J. Conn in 1928. This bacteria was initially found in large quantities in various types of soil. 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. These bacteria have cell walls that contain polysaccharides (with monomers glucose, galactose, and rhamnose), peptidoglycan, and phosphorus. They may also have flagella as well. Notably, ''A. globiformis'' and its antigens and proteins are commercially available for use in research, food production, biodegradation, and water/wastewater treatment. Metabolism ''A. globiformis'' can break down substances in the soil such as agricultural chemicals, chromium, etc. They are primarily aerobic, but ...
