  • Patent number: 8835665
    Abstract: Methods for recovery of recyclable water and/or fermentation co-products from thin stillage process streams. Microbial metabolites plant derivatives and/or plant extractives are removed from thin stillage after which water is recovered and recycled. Thin stillage is commingled with polar organic solvents or with oil to react microbial metabolites, plant derivatives and/or plant extractives. The reacted organic solvents are then separated from the processed thin stillage. Thin stillage may be commingled with an oil to re act with certain organic compounds, after which, the reacted oil is separated from the processed thin stillage is further extracted with one or more polar organic solvents. Alternatively, thin stillage may be first processed with one or more polar organic solvents, and then processed with an oil. Useful organic compounds may be recovered from the reacted oil and reacted organic solvents.

  • Patent number: 8410010
    Abstract: The present disclosure relates to a process for the production of a base complex catalyst comprising reacting a hydroxide base with a polyalcohol, under vacuum pressure, at a temperature in the range of about 60° C. to about 220° C., wherein the mole ratio of the hydroxide base to the polyalcohol is greater than about 2:1.

  • Patent number: 8383172
    Abstract: Methods for separation and recovery of individual cyclic peptides from plant materials, said method comprising the steps of: (a) extracting an oil from a plant material; (b) separating the extracted oil into a non-polar fraction and a polar fraction; (c) separation and recovery of cyclic peptides from the non-polar fraction, and (d) separation and recovery of cyclic peptides from the polar fraction. The methods are suitable for separation and recovery of individual cyclolinopeptides from flax seed oil. Individual cyclolinopeptides are useful for modulation physiological disorders associated with apoptosis. Modified flaxseed oils may be produced by commingling flaxseed oils absent cyclolinopeptides, with at least one cyclolinopeptide separated and recovered with the methods disclosed herein.
