My name is Anna Sieber, I am a PhD student at K1-MET in collaboration with BOKU University in Austria. I participated in the last MBP conference where I presented my results on the phage surface display experiments that I performed to find some Ni(II)-binding peptides. The idea of this identified metal-binding peptides would be to use them to selectively recover the respective metal ions from lithium-ion batteries black mass after bioleaching. While working on the identification of additional peptides binding to other metal ions, I am also trying to set up a recombinant expression system to produce small peptides. Moving more to material science, immobilizing these peptides on a suitable carrier would enable the selective metal recovery from leachate solutions.
I am a biotechnologist by training and after my master’s degree I was working for a (back then) small startup in research. There we tried to express and purify novel Cas proteins as an alternative for Cas9 and perform cleavage of different targets in vitro. After two years, I went back to university and joined K1-MET and BOKU for my PhD.
