Water-insoluble core-shell fibers of PVA and PPX containing M. luteus or N. winogradskyi were achieved by utilizing wet spinning in combination with CVD. The leaking of bacteria from the fibers is retarded in aqueous solution. The immobilized bacteria were used for sequestration of gold and degradation of nitrite from aqueous solutions. The biosorption of gold lead to encapsulated gold nanoparticles as analyzed by EDX, ICP-MS, and TEM.
