Electron uptake by iron-oxidizing phototrophic bacteria.
Oxidation-reduction reactions underlie energy generation in nearly all life forms. Although most organisms use soluble oxidants and reductants, some microbes can access solid-phase materials as electron-acceptors or -donors via extracellular electron transfer. Many studies have focused on the reduction of solid-phase oxidants. Far less is known about electron uptake via microbial extracellular ...
متن کاملDeposition of banded iron formations by anoxygenic phototrophic Fe(II)-oxidizing bacteria
Figure 1. Wavelength-dependent light intensity at different water depths (indicated by numbers assigned to contour lines). Light intensity is given in percent of surface light intensity, where 100% equals ~30,000 lux (~600 mmol quanta m22 s21), estimated to be 24 h average expected for light intensity on horizontal surface on clear summer day (Thimijan and Heins, 1983). Contour lines were deriv...
متن کاملTransferrin-iron uptake by Gram-negative bacteria.
Members of the families Neisseriaceae, Pasteurellaceae and Moraxellaceae are capable of transferrin-iron acquisition in the absence of siderophore production. They do so via expression of a bi-partite receptor composed of two dissimilar proteins, TbpA and TbpB. Both proteins are surface exposed, iron-regulated and capable of binding transferrin. However, other physiochemical, antigenic, and imm...
متن کاملIron isotope fractionation by Fe(II)-oxidizing photoautotrophic bacteria
Photoautotrophic bacteria that oxidize ferrous iron (Fe[II]) under anaerobic conditions are thought to be ancient in origin, and the ferric (hydr)oxide mineral products of their metabolism are likely to be preserved in ancient rocks. Here, two enrichment cultures of Fe(II)-oxidizing photoautotrophs and a culture of the genus Thiodictyon were studied with respect to their ability to fractionate ...
متن کاملGrowth kinetics of attached iron-oxidizing bacteria.
A model of growth and substrate utilization for ferrous-iron-oxidizing bacteria attached to the disks of a rotating biological contactor was developed and tested. The model describes attached bacterial growth as a saturation function in which the rate of substrate utilization is determined by a maximum substrate oxidation rate constant (P), a half-saturation constant (K(s)), and the concentrati...
