Hydrolyzed sponge is the hydrolysate of sponge obtained by acid, enzyme or other method of hydrolysis. Hydrolyzed Sponge are also called sponge spicules, diatom spicules, water needles, biological microneedles, etc. Sponge is one of the simplest multicellular organisms that grow in the ocean or freshwater environment. It is powdery to the naked eye, and it is a sharp rod-shaped crystal spicule and a blunt spicule under a microscope. This needle-like crystal is a very good adsorbent for impurities. It can not only destroy the protein structure of microorganisms or viruses, but also its negative ion charge can adsorb impurities or precipitate pigments in the solution.
