The rhizobacteria Burkholderia cepacia biosynthesized the new tetrapeptide Cyclo[ N ‐(Lys‐Phe)‐Orn‐Val] (1), a 2,5‐diketopiperazine, and the known siderophore azurechelin (salicylic acid). The structure of 1 was established by means of IR, UV, 1 H and 13 C NMR, double dimension experiments and MS. Copyright © 2006 John Wiley & Sons, Ltd.
