The name cepabactin is proposed for this new siderophore. Comparisons of UV-visible spectra and chromatographic behaviour, together with 1H-NMR spectra, led to the conclusion that cepabactin is 1-hydroxy-5-methoxy-6-methyl-2(1H)-pyridinone, a compound which can be considered as a cyclic hydroxamate, but also as a heterocyclic analogue of catechol. This pyridinone has already been described by other workers as an antibiotic produced by Pseudomonas alcaligenes, and by a soil isolate closely related to Pseudomonas cepacia. Thus, cepabactin appears to act as a siderophore for more than one species of non-fluorescent pseudomonad., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-135-6-1479
