The formation and structures of cystites of Arthrobacter ureafaciens NRIC 0157T induced by antibiotics.
The cystite formation of Arthrobacter ureafaciens NRIC 0157(T) was induced by some antibiotics, and the addition of tetracycline at a lag phase was effective for cystite formation in YPM liquid medium. Cystites differed from vegetative cells in the cell wall structure, protein content, and water content. Furthermore, the characteristics and structures of cystites induced by tetracycline were similar to those of cystites produced by nutritional imbalance in CT medium. Consequently, various triggers would induce cystite formation. It is interesting that cystite formation was found in part of the Arthrobacter strains and seemed to correlate with the type of peptidoglycan.
