Uncultured Members of the Oral Microbiome. [PDF]
, 2016 Around one-third of oral bacteria cannot be cultured using conventional methods. Some bacteria have specific requirements for nutrients while others may be inhibited by substances in the culture media or produced by other bacteria.

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 ...

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

Microbial Biotechnology, Volume 18, Issue 8, August 2025.Mediator‐based extracellular electron transfer in Pseudomonas putida KT2440 relies on the TonB‐dependent system for effective mediator (ferricyanide) transport. Transcriptomic and functional analyses confirmed its key role, while OprF overexpression enhanced membrane permeability and current output. These findings clarify mediator uptake mechanisms and

Succinopyoverdins - a New Variety of the Pyoverdin Chromophore
Zeitschrift für Naturforschung C, 2000 Abstract Pseudomonas spp. of the fluorescent group produce siderophores (so-called pyoverdins) consisting of a peptide chain attached to a pyrimidoquinoline ring system which is derived from a condensation product of L-Dab and D-Tyr. Commonly several related compounds are found to accompany the pyoverdins having the same peptide chain ...

Pseudomonas aeruginosa Performs Chemotaxis to All Major Human Neurotransmitters
Microbial Biotechnology, Volume 18, Issue 8, August 2025.Schematic representation of the Pseudomonas aeruginosa chemoreceptors that mediate chemotaxis to ten different human neurotransmitters. Chemoeffectors in back were shown to bind directly to the dCache type ligand binding domains of the corresponding chemoreceptor.
