Photolysis of iron-siderophore chelates promotes bacterial-algal mutualism.
Marine microalgae support world fisheries production and influence climate through various mechanisms. They are also responsible for harmful blooms that adversely impact coastal ecosystems and economies. Optimal growth and survival of many bloom-forming microalgae, including climatically important dinoflagellates and coccolithophores, requires the close association of specific bacterial species...
متن کاملUse of Iron Chelates
U s e of chelating agents--especially the new compound Fe 1 3 8 t o correct iron chlorosis by effectively supplying iron to plants has proved promising in a series of experiments. All plant species tested-but not all individual plants-responded to treatment, and some of the individuals within species did respond with retreatment. Treatment responses in the field have lasted from two to six mont...
متن کاملSynthesis and Characterization of Iron Oxide Nanoparticles by Thermal Decomposition Method of Iron (III) Chelates
Magnetic iron oxide nanoparticles have numerous applications in the biomedical field. This paper reports the preparation and properties of iron oxide nanoparticles synthesised by thermal decomposition method from iron chelates. The iron oxide nanoparticles were characterized by FTIR, powder XRD, VSM, SEM and TEM techniques. FTIR and powder XRD studies show that iron oxide was fo...
متن کاملIron(III) complexation by Vanchrobactin, a siderophore of the bacterial fish pathogen Vibrio anguillarum.
The bacterial fish pathogen Vibrio anguillarum serotype O2 strain RV22 produces the mono catecholate siderophore Vanchrobactin (Vb) under conditions of iron deficiency. Vb contains two potential bidentate coordination sites: catecholate and salicylate groups. The iron(III) coordination properties of Vb is investigated in aqueous solutions using spectrophotometric and potentiometric methods. The...
متن کاملBacterial protection of beetle-fungus mutualism.
Host-microbe symbioses play a critical role in the evolution of biological diversity and complexity. In a notably intricate system, southern pine beetles use symbiotic fungi to help overcome host-tree defenses and to provide nutrition for their larvae. We show that this beetle-fungal mutualism is chemically mediated by a bacterially produced polyunsaturated peroxide. The molecule's selective to...
