  • Enzymatic production of peracids using perhydrolytic enzymes
    Patent number: 8163801
    Abstract: A process is provided to produce a concentrated aqueous peracid solution in situ using at least one enzyme having perhydrolase activity in the presence of hydrogen peroxide (at a concentration of at least 500 mM) under neutral to acidic reaction conditions from suitable carboxylic acid esters (including glycerides) and/or amides substrates. The concentrated peracid solution produced is sufficient for use in a variety of disinfection and/or bleaching applications.
    Type: Grant

  • Lyophilized bioluminescent bacterial reagent for the detection of toxicants
    Patent number: 5731163
    Abstract: A reagent, useful in the detection of environmental insults comprising bacterial cells containing a stress promoter operably linked to a lux gene complex has been prepared by lyophilizing the cells in a specified medium. The reagent may be used immediately upon rehydration where a positive test for the presence of an environmental insult is given by an increase in light production from the cells.
