Abstract:
A proteinaceous extract which has antibacterial activity against gram-negative bacteria made by the process of:extracting seeds from Tagetes sp. or Capsicum sp with an aqueous solution to form a first supernate and insolubles,separating the first supernate from the insolubles;adding ammonium sulfate to 30% relative saturation as a precipitating agent thereby precipitating a first fraction and forming a second supernate;collecting the second supernate;adding amonium sulfate to 70% relative saturation as a precipitating agent thereby precipitating a second fraction and forming a third supernate;dissolving the second precipitate fraction in an aqueous medium;heating the aqueous medium, which contains the second precipitate fraction, to 80.degree. C. thus forming a third precipitate and a third supernate;separating the third supernate;dialyzing the third supernate using a 1000 Dalton molecular weight cut off membrane; andcollecting the dialyzed supernate which does not pass through the membrane.
