ABSTRACT

WEED, LAWRENCE L. (Western Reserve University, Cleveland, Ohio). Effects of copper on Bacillus subtilis. J. Bacteriol. 85:1003–1010. 1963.—Variants have been isolated from liquid cultures of Bacillus subtilis 168 after exposure to copper. The variations manifested are in terms of loss of capacity to be transformed from tryptophan auxotrophy to prototrophy as shown by variant NTCu, and in terms of colony size and altered base composition of the deoxyribonucleic acid as shown by variant SC-22. In addition to the data on altered morphology and chemical composition of the variants, detailed studies on the reversion of one of the variants to B. subtilis are presented.
