  • Publication number: 20140323616
    Abstract: A process for manufacturing eggshell powder for use in the production of bio-based products is provided. The process involves exposing a quantity of eggshell to high air speed at room temperatures to pulverize the eggshell and separate the eggshell component from the inner membrane component. Thus, the process avoids the use of high temperatures and other harsh chemical treatments to remove the inner membrane from the eggshell thereby resulting in an eggshell material that retains the original lipid-protein structure of the native eggshell from which the powder derives. Accordingly, an eggshell powder composition is provided that is substantially free of inner membrane material and possesses a lipid-protein structure substantially similar to that of the eggshell from which the powder is derived. A polymer composite composition comprising an eggshell component and a polymer component is also provided.

  • Patent number: 6818686
    Abstract: The invention relates to a water based polymer composition comprising a biopolymer and a synthetic polymer resin. The biopolymer results from a mechanical thermoplastic processing of a polysaccharide and/or protein starting material using shear forces in the presence of a crosslinking agent. The synthetic polymer resin consists of a water based hydrophilic resin and/or hydrophilic/hydrophobic resin. These compositions have a good storage stability. They are intended for the production of coatings with fair properties.

  • Patent number: 6719973
    Abstract: Recombinant fragments of Factor C are disclosed. These proteins and peptides show great potency in recognizing, binding to, neutralizing and removing endotoxin. These molecules can thus be used for anti-microbial, anti-endotoxin, and anti-sepsis therapy. SSCrFCES is a 38 kDa protein representing the LPS-binding domain of Factor C. The ability of SSCrFCES to bind lipid A was analyzed using an ELISA-based assay as well as surface plasmon resonance. Surface plasmon resonance similarly carried out for SSCrFC-sushi-1,2,3-GFP, SSCrFC-sushi-1GFP, and SSCrFC-sushi-3GFP confirmed their superior affinity for endotoxin. The 50% endotoxin-neutralizing concentration of SSCrFCES against 200 EU of endotoxin is 0.069 &mgr;M, suggesting that SSCrFCES is an effective inhibitor of LAL coagulation cascade.
