Arabidopsis Thaliana Transformed With Streptanthus Farnsworthianus Metal Tolerance Protein 1 (Sfmtp1) Or The Native A. Thaliana Metal Tolerance Protein 1 ( Atmtp1) Cdna And The Effects On Sod Enzyme Activity Upon Nickel Treatment, Selina Urbina Fernandez
Theses and Dissertations
Superoxide Dismutase enzyme activity was analyzed in transgenic Arabidopsis thaliana, a non-accumulator weed plant species of the Brassicaceae family, that was transformed with Streptanthus farnsworthianus Metal Tolerance Protein1 (SfMTP1) or A. thaliana Metal Tolerance Protein 1 (AtMTP1 ). The transgenic A. thaliana was exposed to a 12 day treatment of 100 ?M Nickel Acetate in 1/10 X Hoaglands solution in hydroponics. Analysis of Super Oxide Dismutase activity determined that transgenic A. thaliana transformed with the AtMTP1 cDNA and treated with 100 µM Nickel showed a significant increase in Super Oxide Dismutase activity compared to A. thaliana …
Removal Of Chromium(Vi) And Chromium(Iii) Ions From Aqueous Solution Using Bio-Char Generated From Agricultural Waste Products, Diego Fernando Gonzalez
Removal Of Chromium(Vi) And Chromium(Iii) Ions From Aqueous Solution Using Bio-Char Generated From Agricultural Waste Products, Diego Fernando Gonzalez
Theses and Dissertations
Heavy metals are one of the most persistent and prevalent contaminants in the aquatic environment. The removal of chromium from aqueous solution, especially in the hexavalent form is difficult. New technologies, techniques and/or new materials have been designed in order to effectively and efficiently remove chromium from the aqueous environment. The project focuses on the comparison of the effects of pH, time, temperature, binding capacity on bio-char’ generated from agricultural waste produces vs an amino modified derivative of the bio-char. Pineapple skins were dried, ground, sieved, and pyrolyzed to produce a bio-char material. The bio-char was analyzed using FTIR to …
