Effect of exogenous siderophores on iron uptake activity of marine bacteria under iron-limited conditions.
More than 60% of species examined from a total of 421 strains of heterotrophic marine bacteria which were isolated from marine sponges and seawater were observed to have no detectable siderophore production even when Fe(III) was present in the culture medium at a concentration of 1.0 pM. The growth of one such non-siderophore-producing strain, alpha proteobacterium V0210, was stimulated under i...
متن کاملOligotrophic Bacteria Enhance Algal Growth under Iron-Deficient Conditions.
A Halomonas sp., a marine halophilic and oligotrophic bacterium, was grown on exudates of Dunaliella bardawil. The bacteria increased the solubility of Fe, thereby enhancing its availability to the algae. As a result, the algal growth rate increased. Because of these syntrophic relations, growth of the marine alga D. bardawil was facilitated at Fe levels that would otherwise induce Fe deficienc...
متن کاملThe Burkholderia cepacia fur gene: co-localization with omlA and absence of regulation by iron.
The ferric uptake regulator (Fur) functions as a transcription repressor of many genes in bacteria in response to iron, but the presence of a functional equivalent of this protein has not been demonstrated in Burkholderia cepacia. A segment of the Burkholderia pseudomallei fur gene was amplified using degenerate primers and used to identify chromosomal restriction fragments containing the entir...
متن کاملBurkholderia pseudomallei modulates host iron homeostasis to facilitate iron availability and intracellular survival
BACKGROUND The control over iron homeostasis is critical in host-pathogen-interaction. Iron plays not only multiple roles for bacterial growth and pathogenicity, but also for modulation of innate immune responses. Hepcidin is a key regulator of host iron metabolism triggering degradation of the iron exporter ferroportin. Although iron overload in humans is known to increase susceptibility to Bu...
متن کاملIs Soil Home to Burkholderia cepacia ?
This question has two related components: (1) what is proper identification of Burkholderia cepacia, and (2) what is the evidence of soil as a suitable home for members of this species cluster. The former question has both scientific and practical components. With regard to the latter, a problem arises from the rather casual identification of a great many soil isolates as B. cepacia because of ...
