Identifying the mediators of intracellular E. coli inactivation under UVA light: The (photo) Fenton process and singlet oxygen
César Pulgarin, Stefanos Giannakis
Solar disinfection (SODIS) was probed for its underlying mechanism. When Escherichia coli was exposed to UVA irradiation, the dominant solar fraction acting in SODIS process, cells exhibited a shoulder before death ensued. This profile resembles cell killi ...
PERGAMON-ELSEVIER SCIENCE LTD2022Common reef-building coral in the Northern Red Sea resistant to elevated temperature and acidification
Anders Meibom, Stéphane Laurent Escrig, Thomas Krüger, Maoz Fine, Julia Marie Jeanne Yvonne Bodin, Maria-Evangelia Giovani
Coral reefs are currently experiencing substantial ecological impoverishment as a result of anthropogenic stressors, and the majority of reefs are facing immediate risk. Increasing ocean surface temperatures induce frequent coral mass bleaching events—the ...
Royal Soc2017Kleptoplasty in a shallow water benthic foraminifer, Haynesina germanica
Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin
Some benthic foraminifera have the ability to incorporate functional chloroplasts from diatoms (kleptoplasty). Our objective was to investigate kleptoplast cellular organisation, functionality (O2 flux, C and N incorporation), pigment composition and photo ...
2016A Pyridine-Based Ligand with Two Hydrazine Functions for Lanthanide Chelation: Remarkable Kinetic Inertness for a Linear, Bishydrated Complex
To study the influence of hydrazine functions in the ligand skeleton, we designed the heptadentate HYD ligand (2,2',2 '',2 ''-(2,2'-(pyridine-2,6-diyl)bis(2-methylhydrazine-2,1,1-triyl)) tetraacetic acid) and compared the thermodynamic, kinetic, and relaxa ...
American Chemical Society20152D Fourier Transform Spectroscopy Setup and Ultrafast Dynamics of Porphyrins
The first section of the thesis discusses the development and implementation of a two dimensional Fourier transform spectroscopy setup, that permits the recording of electronic 2D spectra in the visible regime. A hollow core fiber was used to generate broa ...
