The gingipains are cell surface Arg-and Lys-specific proteinases of the bacterium
Porphyromons gingivalis, which has been associated with periodontitis, a disease that …

Aims: To evaluate the suitability of chrome azurol S (CAS) agar plate assay as a quantitative
methodology for siderophore production. Methods and Results: Aspergillus species (A …

Under iron‐limiting conditions, Pseudomonas aeruginosa produces a siderophore called
pyoverdine. Pyoverdine is secreted into the extracellular environment where it chelates iron …

In response to low iron availability, Vibrio parahaemolyticus synthesizes and secretes a
polyhydroxycarboxylate-type siderophore vibrioferrin which is composed of 1 mol each of 2 …

Of all the terminal electron acceptors, Fe (III) is the most naturally abundant in many
subsurface environments. Fe (III)-reducing microorganisms are phylogenetically diverse and …

Natural colloids are abundant in seawater and are an intermediary in the fate, transport and
bioavailability of many trace elements. Knowledge of the pathways and mechanisms of the …

Microorganisms and plants sustain themselves under iron-deprived conditions by releasing
siderophores. Among others, fluorescent pseudomonads are known to exert extensive …

Bacillus subtilis is able to synthesize a lipopeptide biosurfactant (known as surfactin), which
is one of the most effective biosurfactants available. In our previous study, B. subtilis ATCC …

PCR‐based subtractive hybridization was used to isolate genes preferentially expressed in
a termite (Mastotermes darwiniensis) following exposure to an entomopathogenic fungus …

Chelator-buffered hydroponic solutions provide low and buffered free-metal concentrations
and allow the easy calculation of nutrient species expected in these solutions. Some …
