ABSTRACT:
Foamable hydrolyzed proteins substantially free from lipid, nucleic acids, and nucleic acid related substances are obtained by decomposing microbial cells with an alkaline aqueous solution containing an alkaline earth metal hydroxide and an alkali metal hydroxide. The hydrolyzed proteins are useful as foaming agents, especially fire-extinguishing foams effective against fires of oils. The starting microbial cells are available at low cost in great quantities.
