title: Cystite formation of Arthrobacter ureafaciens NRIC 0157(T).
abstract: The cystite formation of Arthrobacter ureafaciens NRIC 0157(T) was studied by the use of a newly designed CT medium composed of 2.0% D-glucose, 0.28% NH(4)H(2)PO(4), 0.136% K(2)HPO(4) 0.136% KH(2)PO(4), 0.0005% MgSO(4).7H(2)O, and 0.0007% CaCl(2).2H(2)O. Cystites are drumstick-shaped and oval cells and are larger than vegetative cells. Cystites are Gram-negative, whereas vegetative cells are Gram-positive by the KOH reaction. The concentration and ratio of K(+) and Mg(2+) in CT medium mainly affected the cystite formation. Cystites are considered aberrant forms produced by nutritional imbalance.
