Silica-alginate-fungi biocomposites for remediation of polluted water

Here we introduce an assembly for bioremediation of polluted water based on the immobilization of alginate beads loaded with filamentous fungus Stereum hirsutum inside nanoporous silica hydrogels. The resulting hybrid device exhibits good physical, chemical and biological stability, being effective...
