  • Patent number: 6105786
    Abstract: A process is disclosed for preparing a detergent powder containing enzymes where the enzymes are extracted from a fermentation broth with a salt and surfactant mixture and directly agglomerated with detergent paste and dried to form the detergent powder. The process results in a two phase system where the enzyme is extracted into the surfactant rich phase and the second phase is salt rich. The process is especially useful for whole or clarified fermentation broths.

  • Patent number: 5622698
    Abstract: Ice nucleating agents are introduced into or on invertebrates. They elevate the supercooling point of such invertebrates. Where such invertebrates are freeze-intolerant, they may be killed or made susceptible to freezing by subjecting them to temperatures at or below the elevated supercooling point. Food sources treated with ice nucleating agents can be used to introduce the agents effectively to the invertebrate.

  • Patent number: 5434072
    Abstract: A method for preparing an aqueous solution enriched in xylanase only, EG III only and both EG III and xylanase from an aqueous mixture containing cellulase proteins, xylanase and EG III is disclosed. The methods involve adding an amount of a low molecular weight alcohol and an organic salt to an aqueous mixture containing cellulase proteins under conditions wherein substantially all of the cellulase proteins other than EG III and xylanase are precipitated out of the aqueous mixture. The methods can then involve adding an inorganic salt to the supernate produced in the previous step so as to form a second precipitate and a second supernate and then finally collecting either the second precipitate from the second supernate to obtain a precipitate enriched in xylanase or the second supernate from the second precipitate to obtain a supernate enriched in EG III.
