Abstract

Bulen, William A. (Charles F. Kettering Foundation, Yellow Springs, Ohio). Effect of tungstate on the uptake and function of molybdate in Azotobacter agilis. J. Bacteriol. 82:130–134. 1961.—The reported competitive inhibition of molybdate by tungstate was investigated in an effort to elucidate molybdenum functions associated with nitrogen fixation by Azotobacter agilis (A. vinelandii). Growth, respiration, and N215-incorporation experiments with normal and molybdenum-deficient cells indicated that tungstate inhibits the uptake of molybdate but does not compete with the metabolically functional molybdenum of cells metabolizing N2. Neither a molybdenum requirement nor a tungstate inhibition was observed with cells metabolizing urea.
