Impact of Lignosulfonate on Solution Chemistry and Phospholipid Fatty Acid Composition in Soils

Pedosphere 2014年第3期24卷 308-321页

作者： .R.almS A.K.AFANOU T.KROGSTAD Norwegian University of Life Science Department of Environmental Sciences P.O.Box 5003 N-1432s (Norway) National Institute of Occupational Health Department of Chemistry and Biology P.O.Box 8149 Dep N-0033 Oslo (Norway) Norwegian University of Life Science Department of Environmental Sciences P.O.Box 5003 N-1432 s (Norway)

An incubation experiment(Exp. 1) with three soils, two from Australia and one from Norway, was carried out to investigate the fate of dissolved BorreGro(a lignosulfonate, produced by Borregaard LignoTech Company, Norway) at different concentrations(0, 10 and 100 mg C L-1) in soil solutions. A rhizobox experiment(Exp. 2) was also done in a Norwegian clay soil, mixed with four levels of BorreGro-carbon(BG-C) added(0, 2, 20 and 200 mg BG-C kg-1) to test the impact of BorreGro on root growth, rhizosphere chemistry(pH, metals and dissolved organic carbon(DOC)) and the composition of phospholipid fatty acids(PLFAs). The BorreGro addition increased the concentration of Mn due to the high concentrations in BorreGro. The BorreGro addition to soil had an indirect but significant impact on the rhizosphere chemistry and PLFAs. The lowest amounts of added BorreGro facilitated the DOC excretion at plant roots, and thereby increased the bacterial and fungal biomass, likely as an effect of increased Mn solubility from BorreGro in the root zone.

Preparation of multi-color quantum dots and its application to immunohistochemical analysis

引用

Chinese Science Bulletin 2008年第13期53卷 2077-2083页

作者： ZHANG BingBo LIU XuHui LI dena TIAN Hui MA GuiPing CHANG Jin Institute of Nanobiotechnology School of Materials Science & Engineering Tianjin University Tianjin 300072 China Center of Technology Beijing Entr-exit inspection and Quarantine Bureau Beijing 100029 China

Quantum dots (QDs) have the potential to be used in the multiplexed bioanalysis for their unique property:multi-color QDs can be excited at the same single wavelength light. In this work,high quan-tum yield multi-color core/shell QDs were prepared. After being water-solubilized by amphiphilic polymer based on self-assembling,the QDs would be labeled by two different IgGs and used in the multiplexed biodetection. Fluorescence resonance energy transfer (FRET) should be avoided in the multiplexed biodetection. In this work,spectral analysis showed that no FRET appeared in water-soluble QDs modified by amphiphilic polymer. The immunofluorescence in vitro indicated that the QDs-IgGs bioconjugates had excellent species-specific detection ability with nearly non-specific binding. The setting of this model will help to support the application of multi-color QDs in the multiplexed bioanalysis communities.
