Advanced bio-composite materials for water treatment

Raff, J.; Pollmann, K.

Abstract

Bacteria developed during evolution highly effective mechanisms and structures to survive at the most forbidding, uninviting places on Earth. One example is the binding of metalloids, heavy metals and actinides by cell surface proteins of uranium mining waste pile isolates. The so called surface layer (S-layer) proteins avoid the uptake and any sustainable damage of the cell by toxic and/or radioactive elements. The proteins possess additionally self-assembling properties and form symmetric lattices. These properties altogether qualifies the protein for nano-technological purposes and allow the production of advanced bio-composite materials such as metal filters, (photo)catalysts, functionalized membranes or biosensors for the treatment of water.

Keywords: S-layer; photocatalysts; water treatment
