  • Patent number: 7833778
    Abstract: The present invention describes a method for producing butanol by fermentation of carbohydrates using mixed populations of acidogenic-phase cells and solventogenic-phase cells of Clostridium in a solitary vessel. The present system as described does not require intermittent adjustment of pH or venting of headspace gases. The method provides a process for removal of the butanol product which does not irreversibly harm the cells and conditions are described where such cells may resume butanol synthesis in the same solitary vessel. The invention also describes compositions and biologically pure cultures which comprise the Clostridium cells as disclosed. Also, a biologically pure Clostridium beijerinkii strain NRRL No. B-50244 is disclosed.

    Abstract: A system and method for identifying a botulinum neurotoxin inhibitor employing a botulinum neurotoxin substrate complex having a peptide substrate, preferably SNAP-25, a reporter domain on one side of said peptide substrate and an immobilization domain on the opposite side of said peptide substrate. The botulinum neurotoxin inhibitor is identified by its ability to decrease the relative amount of cleaved complex, detected through measuring a decrease in complex bound to a solid support. The method of the present invention also utilizes novel cells that express a botulinum neurotoxin substrate complex. The methods of the present invention are adapted for cell based screening to monitor the catalytic activity of a BoNT in living cells and to identify molecules that inhibit the catalytic activity of a BoNT in living cells.

  • Patent number: 7459164
    Abstract: This invention relates to a composition of botulinum based pharmaceuticals used for therapeutic and cosmetic treatment. This invention offers an improvement on the prior art by eliminating the potential of blood-borne contamination with botulinum based pharmaceuticals. Recombinant serum albumin is taught for use in the place of human serum albumin as a stabilizing or enhancing agent.

  • Patent number: 7452543
    Abstract: A class of novel agents that are able to modify nociceptive afferent function is provided. The agents may inhibit the release of neurotransmitters from discrete populations of neurones and thereby reduce or preferably prevent the transmission of afferent pain signals from peripheral to central pain fibers. They comprise a galactose-binding lectin linked to a derivative of a clostridial neurotoxin. The derivative of the clostridial neurotoxin comprises the L-chain, or a fragment thereof, which includes the active proteolytic enzyme domain of the light (L) chain, linked to a molecule or domain with membrane translocating activity. The agents may be used in or as pharmaceuticals for the treatment of pain, particular chronic pain.

  • Patent number: 7445914
    Abstract: Media and processes for the fermentation of Clostridium botulinum and obtaining a botulinum toxin for use in formulating botulinum toxin pharmaceutical compositions. The growth media can contain significantly reduced levels of meat or dairy by-products using non-animal based products to replace the animal-derived products. Preferably, the media used are substantially free of animal derived products.

  • Patent number: 7431935
    Abstract: The invention features a polypeptide complex synthesized by bacteria of the genus Clostridia that contains the serotype E botulinum neurotoxin and five neurotoxin associated polypeptides having molecular weights of about 118, 80, 65, 40, and 18 kDa. respectively. The complex is useful in the treatment of diseases or conditions that are caused by excessive release of acetylcholine from presynaptic nerve terminals.
