Investigation of different methods in siderophore measurement in indigenous Fluorescent Pseudomonads [PDF]

Biological Journal of Microorganism, 2017
Introduction:Fluorescent pseudomonads produced a variety of siderophores in which the pyoverdine type siderophore is the main one. These bacteria employ siderophores to increase availability of Iron for their own and plants consumption. Siderophores have

Fluorescent Pseudomonad Pyoverdines Bind and Oxidize Ferrous Ion [PDF]

Applied and Environmental Microbiology, 1998
ABSTRACT Major pyoverdines from Pseudomonas fluorescens 2-79 (Pf-B), P. aeruginosa ATCC 15692 (Pa-C), and P. putida ATCC 12633 (Pp-C) were examined by absorption and fluorescence spectroscopic techniques to investigate the interaction between ferrous ion and ...

The role of iron in Mycobacterium smegmatis biofilm formation: The exochelin siderophore is essential in limiting iron conditions for biofilm formation but not for planktonic growth [PDF]

, 2007
Many species of mycobacteria form structured biofilm communities at liquid-air interfaces and on solid surfaces. Full development of Mycobacterium smegmatis biofilms requires addition of supplemental iron above 1 μM ferrous sulphate, although addition of

Attenuated Strains of Pseudomonas aeruginosa: A Promising Cell Factory for Rhamnolipid Production

Microbial Biotechnology, Volume 18, Issue 11, November 2025.
PGN strains are generated by the deletion of virulence factor genes. The metabolic pathways and regulatory frameworks that lead to high‐efficiency production of rhamnolipids in P. aeruginosa are preserved in these strains. Therefore, PGN strains are promising bio‐safe cell factories for the industrial production of rhamnolipids.

Characterization of Ocular Clinical Isolates of Pseudomonas aeruginosa from Non-Contact Lens Related Keratitis Patients from South India

Microorganisms, 2020
P. aeruginosa is the most common Gram-negative organism causing bacterial keratitis. Pseudomonas utilizes various virulence mechanisms to adhere and colonize in the host tissue.

Pyoverdin is essential for virulence of Pseudomonas aeruginosa [PDF]

Infection and Immunity, 1996
The role of pyoverdin, the main siderophore in iron-gathering capacity produced by Pseudomonas aeruginosa, in bacterial growth in vivo is controversial, although iron is important for virulence. To determine the ability of pyoverdin to compete for iron with the human iron-binding protein transferrin, wild-type P. aeruginosa ATCC 15692 (PAO1 strain) and

Siderophore-based detection of Fe(iii) and microbial pathogens [PDF]

, 2012
Siderophores are low-molecular-weight iron chelators that are produced and exported by bacteria, fungi and plants during periods of nutrient deprivation.

Effects on LuxR‐Regulated Bioluminescence of Cyclodextrin‐Acyl‐L‐Homoserine Lactone Hybrids

ChemBioChem, Volume 26, Issue 19, October 3, 2025.
Cyclodextrin‐N‐acyl‐L‐Homoserine‐Lactone conjugates are synthetized, purified and fully characterized. The study of modulation of LuxR‐regulated bioluminescence production has demonstrated that one of the compounds exhibits not only the capacity to induce bioluminescence with an EC50 value of 64 µM, but also the ability to reduce bioluminescence with ...

Reconstruction of the metabolic network of Pseudomonas aeruginosa to interrogate virulence factor synthesis [PDF]

, 2017
Virulence-linked pathways in opportunistic pathogens are putative therapeutic targets that may be associated with less potential for resistance than targets in growth-essential pathways.
