  1. 11. Potential use of Rhizobium spp. to improve growth of non-nitrogen fixing plants

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Md. Shakhawat Hossain; [2007]
    Nyckelord :nitrogen fixation; plant growth promoting bacteria; rhizosphere interactions; soil biology;

    Sammanfattning : Plant growth promoting rhizo-bacteria (PGPR) affect plant growth by producing and releasing secondary metabolites (plant growth regulators/phytohormones/biologically active substances), facilitating the availability and uptake of certain nutrients from the root environment and inhibiting plant pathogenic organisms in the rhizosphere. At the same time, plants produce root exudates containing e. LÄS MER

  2. 12. Degradation of aged creosote and diesel contaminated soils by phytoremediation or biostimulation (nutrients)

    L3-uppsats, SLU/Dept. of Soil Sciences

    Författare :Nghia Nguyen Khoi; [2007]
    Nyckelord :creosote; diesel fuel; PAHs; benzo fluoranthene; benzo pyrene; phenathrene; bioremediation; phytoremediation; salix clones;

    Sammanfattning : Aged creosote and diesel fuel polluted soil was collected from Resecentrum, Uppsala (deposited at Hovgården). The aims of this study were: 1) to compare the growth and degradation of PAHs and diesel by five Salix clones and 2) to study the effect of nutrients on biodegradation of PAHs and diesel. LÄS MER
