Transition Metal Ions at the Crossroads of Mucosal Immunity and Microbial Pathogenesis [PDF]

open access: yesFrontiers in Cellular and Infection Microbiology, 2014
Transition metal ions are essential micronutrients for all living organisms. In mammals, these ions are often protein-bound and sequestered within cells, limiting their availability to microbes. Moreover, in response to infection, mammalian hosts further

Adsorption of metal ions on lignin [PDF]

open access: yesJournal of Hazardous Materials, 2008
This study investigated the adsorption of the heavy metal ions Pb(II), Cu(II), Cd(II), Zn(II), and Ni(II) on a lignin isolated from black liquor, a waste product of the paper industry. Lignin has affinity with metal ions in the following order: Pb(II)>Cu(II)>Cd(II)>Zn(II)>Ni(II).
