ATOPFe - NEW EXPERIMENTS ON Fe AND Cu BIOAVAILABILITY: NEW SCENARIOS IN THE FUTURE OCEANS BY M. MALDONADO
I have enjoyed tremendously my stay in the QUIMA lab of Profs. Magdalena Santana-Casiano and Melchor Gonzalez-Davila this April (2018). I have learnt so much from everyone! I send my warmest thank you to all members of the QUIMA lab, especially to Aridane Gonzalez and Carolina Santana Gonzalez, as well as Profs. Melchor Gonzalez and Magdalena Santana. I have furthered my knowledge and experience with competitive ligand exchange-adsorptive cathodic stripping voltammetry (CLE-ACSV), using the BAS i Controlled Growth Mercury Electrodes (CGME) voltammeter. We have focused on measuring organic complexation of Cu, as well as designing and executing experiments to measure the kinetics of Fe and Cu adsorption to phytoplankton cell surfaces. With this work we aim to establish the density, kinetic constants and conditional stability constants of metal transporters specific for Cu and Fe at the cell surface of phytoplankton. This month, as a start, we used the diatoms, Phaeodactylum trico...
