Cybernetic modeling of iron-limited growth and siderophore production.
The cybernetic modeling framework developed by Ramkrishna and co-workers has been applied to a case of bacterial metabolite production, namely the production of siderophores (iron-chelating agents) associated with iron-limiting fermentation conditions. Experimental growth data showed that, even though final biomass levels were controlled by exhaustion of the carbon source, iron-limiting conditi...
متن کاملAn iron-regulated gene required for utilization of aerobactin as an exogenous siderophore in Vibrio parahaemolyticus.
A previous investigation using the Fur titration assay system showed that Vibrio parahaemolyticus possesses a gene encoding a protein homologous to IutA, the outer-membrane receptor for ferric aerobactin in Escherichia coli. In this study, a 5.6 kb DNA region from the V. parahaemolyticus WP1 genome was cloned and two entire genes, iutA and alcD homologues, were identified which are absent from ...
متن کاملSerotypes of Vibrio parahaemolyticus isolates from hydrobiologically dissimilar aquatic environments.
Serological analysis of the O and K antigens was performed on 324 isolates of Vibrio parahaemolyticus obtained from three hydrobiologically dissimilar aquatic environments. Only 50.9% of the strains could be serotyped. The largest number of untypable strains and the lowest serological diversity were observed from the freshwater collection. Three serotypes, O2:K28, O5:K17, and O2:K3, dominated a...
متن کاملVibrio parahaemolyticus growth under low-iron conditions and survival under high-magnesium conditions.
Since 1996, Vibrio parahaemolyticus serotype O3:K6 and closely related strains have been associated with an increased incidence of V. parahaemolyticus gastroenteritis worldwide, suggesting the emergence of strains with enhanced abilities to cause disease. One hypothesis for the recent emergence of V. parahaemolyticus O3:K6 and related strains is an enhanced capacity for environmental survival r...
متن کاملBinding of iron-free siderophore, a common feature of siderophore outer membrane transporters of Escherichia coli and Pseudomonas aeruginosa.
TonB-dependent iron transporters present in the outer membranes of Gram-negative bacteria transport ferric-siderophore complexes into the periplasm. This requires proton motive force and an integral inner membrane complex, TonB-ExbB-ExbD. Recognition of iron-free siderophores by TonB-dependent outer membrane transporters (OMT) has only been described for a subfamily called OMT(N). These OMT(N)s...
