Denitrification in Rhizobium.
Thirty-three strains of Rhizobium were examined for their reduction of nitrate under anoxic conditions. Three patterns of dissimilatory nitrate reduction were observed: (1) reduction to N2O and N2Expand

Nitrate Inhibition of Nodulation and Nitrogen Fixation by Supernodulating Nitrate‐Tolerant Symbiosis Mutants of Soybean
Several soybean mutants that form a greater number of nodules (supernodulation) and display a nitrate tolerant symbiosis (nts) phenotype when grown in sand with continuous additions of NO 3 − haveExpand

Nitrogen fixation, denitrification, and pleomorphic growth in a highly pigmented Spirillum lipoferum.
A strain of Spirillum lipoferum with intense red pigmentation was isolated from the roots of Cynodon dactylon "Coastal." This isolate vigorously reduced acetylene when grown in N-free, Na-malate,Expand
