Arthrobacter sp. - pleomorphic, soil prokaryote (bacterium)

Image Number: 23844C

Caption:

Arthrobacter sp. - Gram-positive to Gram-variable, coryneform, pleomorphic, soil bacterium. This genus is unique because of its unusual habit of "snapping division" in which the outer cell wall ruptures at a joint. This type of cell division in which rods break into cocci is referred to as reversion. Arthrobacter spp. have been found to perform important biodegradable functions in soil and sediment. This strain was isolated from sediment that had high levels of heavy metals. This genus can survive in heavy metal contaminatef soil. Recently it has been shown that several species of Arthrobacter can reduce hexavalent chromium which can cause severe reactions in humans. Some species are also known to biodegrade agricultural herbicides and pesticides.
