Iron acquisition with the natural siderophore enantiomers pyochelin and enantio-pyochelin in Pseudomonas species [PDF]
, 2018 The bacterial siderophore pyochelin is composed of salicylate and two cysteine-derived heterocycles, the second of which is modified by reduction and N-methylation during biosynthesis. In Pseudomonas aeruginosa, the first cysteine residue is converted to

Modulation of siderophore production by Pseudomonas fluorescens through the manipulation of the culture medium composition [PDF]
, 2021 Pseudomonas fluorescens has the ability to produce the siderophore pyoverdine, a biotechnologically significant iron chelator, which has a wide range of potential applications, such as in agriculture (iron fertilizers) and medicine (development of ...

Metagenomic domain substitution for the high-throughput modification of nonribosomal peptides
Nature Chemical Biology, 2023 The modular nature of nonribosomal peptide biosynthesis has driven efforts to generate peptide analogs by substituting amino acid-specifying domains within nonribosomal peptide synthetase (NRPS) enzymes. Rational NRPS engineering has increasingly focused

MicrobiologyOpen, Volume 15, Issue 1, February 2026.This study highlights the prevalence of multidrug‐ and carbapenem‐resistant Pseudomonas aeruginosa in pediatric cystic fibrosis patients, along with the presence of carbapenemase‐encoding genes and genetic profiles, suggesting clonal spread. These findings underscore the urgent need for surveillance and strategies to combat resistant strains and ...

Rhizobactin B is the preferred siderophore by a novel Pseudomonas isolate to obtain iron from dissolved organic matter in peatlands [PDF]
, 2020 Bacteria often release diverse iron-chelating compounds called siderophores to scavenge iron from the environment for many essential biological processes. In peatlands, where the biogeochemical cycle of iron and dissolved organic matter (DOM) are coupled,

Angewandte Chemie, Volume 138, Issue 4, 22 January 2026.Pseudotetraivprolid ist ein neuer Akteur unter den Detoxin/Rimosamid‐ähnlichen Naturstoffen. Die Biosynthese erfordert FabD aus dem Primärstoffwechsel und einen PipDFG‐Komplex für die Acetylierung im letzten Schritt – wodurch schließlich die anti‐antibiotische Wirkung entsteht.

Biogenesis of the Pyoverdin Chromophore
Zeitschrift für Naturforschung C, 1997 Abstract After growing Pseudomonas aeruginosa in the presence of 2 ,4-[4-15N]-diaminobutyric acid (Dab) its incorporation into the quinoline chromophore of the pyoverdin produced by this bacterium could be shown by mass and NMR-spectroscopic techniques.

Pretreatment with solid phase extraction and analysis with liquid chromatography/mass spectrometry for siderophores in seawater [PDF]
, 2015 铁在生物的生命活动中扮演着重要角色，如含铁蛋白在生物的光合作用、呼吸作用、硝酸盐和亚硝酸盐的还原、氮的固定及DNA的合成等过程中都起着不可替代的作用。但是海洋表层的生物可利用态铁浓度极低，影响甚至限制着浮游植物的生长。在铁限制条件下，海洋中的一些细菌和真菌能够合成并分泌一种与铁有极强螯合能力的低分子量有机配体——铁载体。铁载体被释放到细胞外后有效地与铁结合，通过细胞膜上特定铁载体受体的识别和转运，将铁运输到微生物细胞内，以满足生物体对铁的需求。 由于铁载体结构复杂多样，在海洋环境中浓度低，分析相对困难 ...

Microbial Antagonism at the Root Level Is Involved in the Suppression of Fusarium Wilt by the Combination of Nonpathogenic Fusarium oxysporum Fo47 and Pseudomonas putida WCS358 [PDF]
, 1999 Two biological control agents, nonpathogenic Fusarium oxysporum Fo47 and Pseudomonas putida WCS358, were evaluated for suppression of Fusarium wilt of flax grown in nutrient solution and for suppression of the population density and metabolic activity
