Abstract
The sporicidal activity of components used in liquid and solid rocket propellants was tested by use of spores of
Bacillus subtilis
dried on powdered glass. Liquid propellant ingredients tested were N

was immediately sporicidal; the hydrazines were effective within several days. Solid propellants consisted of ammonium perchlorate in combination with epoxy resin (EPON 828), tris-1-(2-methyl) aziridinyl phosphine oxide, bis-1-(2-methyl) aziridinyl phenylphosphine oxide, and three modified polybutadiene polymers. There was no indication of appreciable sporicidal activity of these components.
