Structure of the pyoverdin PVD 2908--a new pyoverdin from Pseudomonas sp. 2908.

An unknown siderophore (pyoverdin) was isolated from the strain Pseudomonas sp. 2908. The structure of the pyoverdin--called PVD 2908--was elucidated by spectroscopic methods and degradation studies. Some other siderophores were identified by LC/ESI-MS-screening based on the knowledge of PVD 2908.
