title: The stereoisomers of pyochelin, a siderophore of Pseudomonas aeruginosa.
abstract: The Pseudomonas aeruginosa siderophore pyochelin is obtained from the bacterial culture medium as a mixture of two epimers. Chromatically isolated pure stereoisomers equilibrate readily in most solvents. Experiments will be reported which allow to isolate one of the isomers in pure form and which shed some additional light on the epimerization reaction.
