Form of selenium in selenite enrichment media for isolation of salmonellae.
Selenite-F and selenite-cystine media, commercially available for the routine isolation of salmonellae, were treated by anion exchange chromatography to separate the selenium from other components of the media. A chemical assay, based on an ascorbic acid reduction, showed that the selenium was all in the form of selenite.
