(Alpha)-keto acids are novel siderophores in the genera Proteus, Providencia, and Morganella and are produced by amino acid deaminases

The production of various alpha-keto acids in the Proteus-Providencia-Morganella group was monitored, and siderophore activity by growth promotion and iron transport assays was examined. Results present evidence that alpha-keto and alpha-hydroxycarboxylic acids proved most suitable for iron nutritio...

Summary:The production of various alpha-keto acids in the Proteus-Providencia-Morganella group was monitored, and siderophore activity by growth promotion and iron transport assays was examined. Results present evidence that alpha-keto and alpha-hydroxycarboxylic acids proved most suitable for iron nutrition in the Proteus-Providencia-Morganella group and may be regarded as typical siderophores of members of the tribe Proteeae.
