Silicic acid, however, is inherently unstable and will rapidly condense with itself with the elimination of water forming dimers , trimers and eventually high molecular weight polymers. ... Silica, (SiO2) can be considered to be the anhydride of silicic acid, and in its naturally occurring crystalline form,

A model procedure has been developed for the rapid extraction of five bacteriocins (nisin, pediocin RS2, leucocin BC2, lactocin GI3, and enterocin CS1) from concentrated freeze-dried crude culture supernatants by adsorption onto acid or alkaline rice hull ash (RHA) or silicic acid (SA).
