VIABILITY OF BACILLUS SUBTILIS SPORES IN ROCKET PROPELLANTS.

R M GODDING, V H LYNCH

    Applied Microbiology
    |January 1, 1965
    PubMed
    Summary

    The sporicidal activity of rocket propellant components was assessed. Nitrogen tetroxide (N2O4) showed immediate sporicidal effects, while hydrazines were effective within days; solid propellant components lacked significant sporicidal activity.

    Area of Science:

    • Astrochemistry
    • Microbiology
    • Materials Science

    Background:

    • Rocket propellants are essential for space exploration.
    • Understanding the antimicrobial properties of propellant components is crucial for mission safety and planetary protection.
    • Bacillus subtilis spores are a robust model for testing sporicidal efficacy due to their resilience.

    Purpose of the Study:

    • To evaluate the sporicidal activity of key ingredients found in liquid and solid rocket propellants.
    • To determine the effectiveness of specific chemicals against Bacillus subtilis spores.

    Main Methods:

    • Spores of Bacillus subtilis were dried onto powdered glass for testing.
    • Liquid propellant components, including Nitrogen tetroxide (N2O4), monomethylhydrazine, and 1,1-dimethylhydrazine, were individually assessed.
    • Solid propellant formulations containing ammonium perchlorate and various binders (EPON 828, aziridinyl phosphine oxides, polybutadiene polymers) were tested.

    Main Results:

    • Nitrogen tetroxide (N2O4) demonstrated immediate sporicidal activity.
    • Monomethylhydrazine and 1,1-dimethylhydrazine exhibited sporicidal effects within several days of exposure.
    • None of the tested solid propellant components showed significant sporicidal activity against Bacillus subtilis spores.

    Conclusions:

    • Liquid rocket propellant ingredients, particularly N2O4 and hydrazines, possess varying degrees of sporicidal activity.
    • Solid rocket propellant components evaluated in this study do not appear to have substantial antimicrobial properties.
    • Further research may be needed to explore synergistic effects or alternative antimicrobial strategies for solid propellants.
