Biomineralization of Uranium-Phosphates Fueled by Microbial Degradation of Isosaccharinic Acid (ISA)
Geological disposal is the globally preferred long-term solution for higher activity radioactive wastes (HAW) including intermediate level waste (ILW). In a cementitious system, cellulosic items present in ILW may undergo alkaline hydrolysis, producing significant quantities of isosaccharinic acid (ISA), chelating agent radionuclides. Although microbial degradation ISA has been demonstrated, it...
phosphate solubilizing bacteria are a group of plant growth promoting rhizobacteria (pgpr) that increase growth and yield of plant by enhancing insoluble phosphates. in this study, a greenhouse experiment was carried out to investigate the effect of phosphate solubilizing bacteria and phosphorous fertilizer on the yield and chemical components of sesame. this experiment was conducted in factori...
We evaluated the inducibility of nitrate-dependent Fe(II)-EDTA oxidation (NDFO) in non-growth, chloramphenicol-amended, resting-cell suspensions of Dechloromonas sp. strain UWNR4 and Acidovorax sp. strain 2AN. Cells previously incubated with Fe(II)-EDTA oxidized ca. 6-fold more Fe(II)-EDTA than cells previously incubated with Fe(III)-EDTA. This is the first report of induction of NDFO by Fe(II).
Relevance. Phosphate mineralization of Devonian intrusions in the Eastern zone Middle Urals is currently poorly understood, data obtained may be important for interpreting origin rocks, especially case when standard methods geochemical analysis rocks do not give a clear picture. Xenotime and monazite are minerals concentrating rare earth elements, REE distribution graphs very characteristic roc...
The Mount Weld rare earth element (REE) deposit, Western Australia, is one of the largest its type on Earth. Current mining exploits high-grade weathered goethite-bearing resource that lies above, and which represents weathering product a subjacent carbonatite. mineralogy, petrography, deportment lanthanides among different components, variation in mineral speciation, textures, chemistry are ex...
[1] Water played a major role in the formation and alteration of rocks and soils in the Columbia Hills. The extent of alteration ranges from moderate to extensive. Five distinct rock compositional classes were identified; the order for degree of alteration is Watchtower ffi Clovis > Wishstone ffi Peace > Backstay. The rover’s wheels uncovered one unusual soil (Paso Robles) that is the most S-ri...
