Immobilization of yeast and bacteria cells in alginate microbeads coated with silica membranes: procedures, physico-chemical features and bioactivity†
Abstract
Salt
alginate beads are used to entrap yeast or bacteria cells and exploited as protective environment for deposition of )4 and 42.7% HO–Si(OSi
)3 units). In this case a linear relation is found among different contact times between
)2OH and H3C–Si(OSi
)3 units in an almost 1 : 1 ratio.
