RESUMO

Blankenship, L. C. (University of Maryland, College Park) and R. N. Doetsch. Influence of a bacterial cell extract upon the morphogenesis of Arthrobacter ureafaciens. J. Bacteriol. 82:882–888. 1961—The effect of a bacterial extract on alleviating the abnormal morphological appearance of Arthrobacter ureafaciens when cultivated in Thiotone broth is described. Physical and chemical analyses of this extract revealed that the mineral components therein were largely responsible for the observed effects. Similar results were obtained using ashed Trypticase soy broth, known mineral mixtures, or magnesium ions. The role played by these materials in governing the morphology of A. ureafaciens is discussed.
