The cystite formation of Arthrobacter ureafaciens NRIC 0157T was studied by the use of a newly designed CT medium composed of 2.0% D-glucose, 0.28% NH4H2PO4, 0.136% K2HPO4, 0.136% KH2PO4, 0.0005% MgSO4·7H2O, and 0.0007% CaCl2·2H2O. 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 Mg2+ in CT medium mainly affected the cystite formation. Cystites are considered aberrant forms produced by nutritional imbalance.
