title: Growth and pigment production by Arthrobacter pyridinolis n. sp.
abstract: A new bacterium capable of growing on 2-hydroxypyridine as sole source of carbon and nitrogen was isolated from soil. During its growth on solid medium, approximately 50% of this substrate was converted to a brilliant blue crystalline pigment which was deposited extracellularly in the colony mass. The pigment was identical to that produced by Arthrobacter crystallopoietes during its growth on 2-hydroxypyridine. The new isolate exhibited the typical cycle of morphogenesis characteristic of the genus Arthrobacter. The organism is different from all other reported species of Arthrobacter. It is proposed that the organism be named Arthorbacter pyridinolis n. sp.
