The present study was initiated to determine the capacity of sulfide minerals (pyrite FeS2 and chalcopyrite CuFeS2) delay migration inorganic selenium species in geological formations. Interactions between SeIV Se-II synthetic natural were investigated under anoxic conditions using batch method. Significant sorption occurred acidic conditions. Analysis solids after Se X-ray photoelectron spectroscopy (XPS) absorption near edge structure (XANES) demonstrated presence reduced on metallic...

Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is a widely used explosive that present in soils at number of military sites, including training and testing ranges. Because its relatively weak adsorption to soil, RDX frequently migrates through the unsaturated zone causes groundwater contamination. In environment, can transform produce mono-, di-, tri-nitroso derivatives (MNX, DNX, TNX) ring cleavage products methylenedinitramine (MEDINA) 4-nitro-2,4-diazabutanal (NDAB). The study was...
Introduction The fungal G protein-coupled receptors Ste2 and Ste3 are vital in mediating directional hyphal growth of the agricultural pathogen Fusarium graminearum towards wheat plants. This chemotropism is induced by a catalytic product peroxidases secreted wheat. Currently, identity this product, substrate it generated from, not known. Methods results We provide evidence that peroxidase derived from F. conidia report simple method to extract purify Fg Ste2-activating ligand for analyses...
Lignin is an intricate phenolic polymer found in plant cell walls that has tremendous potential for being converted into value-added products with the possibility of significantly increasing economics bio-refineries. Although lignin nature bio-degradable, its biocatalytic conversion challenging due to stable complex structure and recalcitrance. In this context, understanding strain's genomics, enzymes, degradation pathways can provide a solution breaking down unlock full as dominant valuable...
The sorption/desorption and long-term fate of octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine (HMX) was examined using sterilized nonsterilized soils. Two soils were used that differ mainly by the amount total organic carbon (TOC): an agricultural topsoil (VT, 8.4% TOC) a sandy soil (SSL, 0.33% TOC). adsorption isotherms performed at room temperature well-described linear model, which led to sorption distribution coefficients 2.5 0.7 L kg-1 for VT SSL soils, respectively. content did not...
CL-20 (2,4,6,8,10,12-hexanitro-2,4,6,8,10,12-hexaazaisowurtzitane), C6H6N12O12, is an emerging energetic chemical that may replace RDX, but its degradation pathways are not well-known. In the present study, zerovalent iron was used to degrade with aim of determining products and pathways. absence O2, underwent a rapid decomposition concurrent formation nitrite ultimately produce nitrous oxide, ammonium, formate, glyoxal, glycolate. LC/MS (ES-) showed presence several key carrying important...
