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 ...

Journal of Veterinary Pharmacology and Therapeutics, Volume 49, Issue 2, Page 220-227, March 2026.ABSTRACT Trailing endpoints are a recognised challenge in broth microdilution MIC testing, particularly for bacteriostatic agents such as trimethoprim (TMP) and sulphonamides. In this study, we applied a pharmacodynamically guided refinement to determine the MIC of the combination against Staphylococcus pseudintermedius; we did not aim at redefining ...

Mechanistic Insights for Microbiome Application in Plant Disease Resistance
Molecular Plant Pathology, Volume 27, Issue 3, March 2026.This review summarises the mechanisms underlying plant‐guided microbiome modulation and probiotic‐mediated disease suppression. Additionally, it highlights the challenges to be addressed for a better microbiome application of disease resistance in sustainable agriculture and proposes possible strategies. Figure was created with BioRender.

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 ...

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 ...

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.

The Pyoverdins of Pseudomonas syringae and Pseudomonas cichorii
Zeitschrift für Naturforschung C, 2004 Abstract The structure elucidation of the cyclic (lactonic) forms of the pyoverdins with a succinamide side chain originally produced by the closely related species Pseudomonas syringae and P. cichorii is reported. Mass spectrometry and nuclear magnetic resonance analyses as well as the determination of the configuration of the amino ...

Ironing out pyoverdine’s chromophore structure: serendipity or design? [PDF]
JBIC Journal of Biological Inorganic Chemistry, 2019 Pyoverdines are Pseudomonas aeruginosa's primary siderophores. These molecules, composed of a fluorescent chromophore attached to a peptide chain of 6-14 amino acids, are synthesized by the bacterium to scavenge iron (essential to its survival and growth) from its environment.

PAMPs, MAMPs, DAMPs and others: an update on the diversity of plant immunity elicitors [PDF]
, 2012 Plants possess a broad array of defenses that could be actively expressed in response of pathogenic organisms or parasites but also following beneficial saprophytic microorganisms recognition.
