The stereoisomers of pyochelin, a siderophore of Pseudomonas aeruginosa
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. Experime...

The structure of a pyoverdine produced by a Pseudomonas tolaasii-like isolate
Cultures of Agaricus bisporus, the most extensively cultivated mushroom, can be infected severely by Pseudomonas tolaasii. This pathogen is characterized by the so-called white line reaction, a precipitate formed...

The structure of a pyoverdine from Pseudomonas sp. CFML 96.188 and its relation to other pyoverdines with a cyclic C-terminus
From Pseudomonas sp. CFML 96.188 a pyoverdine was isolated and its primary structure was elucidated by spectroscopic methods and degradation reactions. This strain is of interest as it accepts the structurally di...

A pyoverdine from Pseudomonas putida CFML 90-51 with a Lys ε-amino link in the peptide chain
From Pseudomonas putida CFML 90-51 – a hospital isolate – a pyoverdine was obtained which is characterized by the unusual linkage by the ε-rather than the α-amino group of Lys in the peptide chain. The structure ...

Neue Siderophore des Pyoverdin-Typs ausPseudomonas fluorescens
The structure of four new pyoverdins (Pf12-IA, -IIA, -IB und IIB) isolated from the culture medium ofPseudomonas fluorescens 12 was elucidated by combination of spectroscopic methods and degradation reactions. Th...
