Investigation of cerium and yttrium ions effects on microbial nitrogen fixation and determination of inhibition.
Critical investigation of the effect of yttrium and cerium ions in culture media for nitrogen-fixing bacteria showed strong inhibition. There was a decrease in the amount of nitrogen fixed; simultaneously, in the samples containing cerium ions, carbon consumption values increased as the molarity of metal ion was enhanced. Inhibition rate was invariably maximum at the highest concentration of metal ions.
