[Serum sterilization in the cold with peracetic acid]
Journal of Hygiene, Epidemiology, Microbiology, and Immunology
|January 1, 1976
Summary
Peracetic acid effectively sterilizes serum for cell cultures, even inactivating bacterial spores, mycoplasmas, and viruses. This cold sterilization method preserves serum quality for microbial and tissue culture applications.
Area of Science:
- Microbiology
- Biotechnology
Context:
- Sterilization of biological materials is crucial for preventing contamination in cell culture and diagnostic assays.
- Traditional sterilization methods like filtration or autoclaving may degrade sensitive biological components in serum.
Purpose:
- To evaluate the efficacy of peracetic acid as a cold sterilization agent for serum used in microbial and tissue culture.
- To assess the impact of peracetic acid sterilization on serum's suitability for supporting cell growth and its immunological properties.
Summary:
- Peracetic acid demonstrates broad-spectrum antimicrobial activity, including against bacterial spores, mycoplasmas, and viruses.
- A final concentration of 0.02-0.1% peracetic acid effectively sterilized serum within 30 minutes to 5 days, enabling its use in bacterial, mycoplasma, and tissue cultures.
- Serum sterilized with peracetic acid supported cell growth comparable to filtered sera, but showed a significant reduction in neutralization and complement fixation antibodies.
Impact:
- Peracetic acid offers a viable cold sterilization alternative for serum, potentially preserving heat-labile components.
- The reduction in antibody titers necessitates careful consideration for applications relying on specific immunological functions of the serum.
