Latest Patents

John J Joung holds a patent for "Biocatalyst immobilization in a gel of anionic polysaccharide." This patent describes a method for preparing an immobilized biocatalyst suitable for fermenting to produce ethanol. The process involves mixing a biocatalyst, such as a microorganism, with a reaction product of a homogeneous dispersion of an anionic polysaccharide, like alginate, and a cationic polymer, such as polyethyleneimine. The resultant dispersion is then combined with an oil phase to form beads. A surfactant may be included during this combination. Additionally, a water-soluble, oil-insoluble curing powder, which includes a salt of a multivalent cation like calcium chloride, is mixed with the beads in the oil phase to gel and dehydrate them. This process prevents the beads from adhering to one another until their surfaces become hardened.
