Rhizobium japonicum SOD was determined to be iron-containing by criteria of sensitivity to 5 mM H2O2 and 1 mM NaN3. Growth media strongly influenced SOD activity. The addition of methyl viologen to cultures of R. japonicum 61A76NS, growing in complex medium, caused induction of the enzyme. Yeast extract was essential for induction of SOD. Puromycin blocked the induction of the enzyme. Rhizobium spp. were surveyed for SOD activity, electrophoretic mobility on polyacrylamide gels, and metal content. }, number={11}, journal={CANADIAN JOURNAL OF MICROBIOLOGY}, author={STOWERS, MD and ELKAN, GH}, year={1981}, pages={1202–1208} }
