Wheat (Triticum aestivum) collected in the Nawanshahr-Hoshiarpur Region (Punjab, India) showed highest selenium concentrations ever recorded cereal grains (29−185 μg g−1). There was a strong positive relationship between content shoots and that kernels, showing grain concentration can be predicted from vegetative tissues of plant. The identity selenocompounds samples wheat-based reference materials were investigated by HPLC−ICP−dynamic reaction cell−MS. Reversed-phase, cation exchange, anion...
Several novel selenium containing compounds were characterized in staple crops (wheat, rice and maize) grown on soils naturally rich selenium. A dedicated method based the coupling of liquid chromatography with multiplexed detection (ICP-MS, ESI-Orbitrap MS(/MS)) was developed for speciation low-molecular weight (<5 kDa) metabolites. Nine species present different proportions as a function crop type identified by cation-exchange HPLC-ESI-Orbitrap MS basis accurate molecular mass MS/MS...
The aim of the study was to explore biogenesis nano-structures through reduction selenium by soil bacterium Pseudomonas aeruginosa. strain under indicated tolerance upto 50 mg L-1, using reductive mechanisms for detoxication, thus biotransforming oxyanions elemental red selenium. Partial characterization AFM biotransformed carried out which formation spherical amorphous allotropic
Heterogeneous photocatalytic degradation and mineralization of Isoproturon (IPU) was investigated in aqueous solutions containing titanium dioxide. The monitored by observing the change absorption intensity UV range through HPLC analysis. rate found to be strongly dependent on catalyst concentration, initial pH, substrate concentration. effect variation irradiations, recycling as well area/volume is also studied for practical applications. observed follow first‐order kinetics. TiO 2 loading...
Majority of the post-harvest agri-residues from agricultural activity in Punjab, India, is burnt field resulting loss soil fertility and release large amounts air pollutants. In an effort to reutilize selenium-accumulated waste wheat paddy straw seleniferous region two varieties edible mushrooms, Pleurotus sajor-kaju Volvariella volvacea, were cultivated on Se-rich straw, respectively. Se concentration Se-enriched P. V. volvacea (43.5 ± 2.1 35.0 1.1 μg/g) was significantly higher than...
Wheatgrass are young saplings of the common wheat plant containing significant amount proteins, vitamins, minerals, and antioxidants like phenols/flavonoids. During its germination growth, many biotic abiotic factors influence nutritional quality wheatgrass. Present work was focused on understanding profile enzymatic nonenzymatic levels in wheatgrass when exposed to selenium (Se) ultraviolet-B (UV-B) radiation. Se-rich grains were used for cultivation under UV-B radiation whereas,...
Many organisms reductively assimilate selenite to synthesize selenoprotein. Although the thioredoxin system, consisting of 1 (TrxA) and reductase with NADPH, can reduce is considered facilitate assimilation, detailed mechanism remains obscure. Here, we show that was reduced by system from Pseudomonas stutzeri only in presence TrxA (PsTrxA), this specific among oxyanions examined. Mutational analysis revealed Cys33 Cys36 residues PsTrxA are important for reduction. Free thiol-labeling assays...
