New Low Temperature Sterilization Processes

Low-temperature sterilization and new technologies.

The new low-temperature sterilization technologies are presented as an alternative to the use of ethylene oxide. This review was performed in order to identify evidences of the antimicrobial activity, toxicity, adverse events and the applicability of these technologies. The research was carried through the electronic databases MEDLINE and LILACS up to 2005. The authors analyzed 10 articles in t...

Low-temperature sterilization using low-temperature steam and formaldehyde

Sporicidal activity of a new low-temperature sterilization technology: the Sterrad 50 sterilizer.

This study was undertaken to evaluate the efficacy of a new low-temperature sterilization system that recently has been cleared by the Food and Drug Administration, the Sterrad 50. Flat stainless steel carriers were inoculated with approximately 10(6) Bacillus stearothermophilus spores. These carriers were placed aseptically in the middle of 40-cm-long stainless steel-lumened test units of vary...

Low temperature air plasma sterilization on Pseudomonas aeruginosa

Low temperature air plasma was used to sterilize the Pseudomonas aeruginosa (P. aeruginosa ATCC15442) samples on the polyethylene terephthalate (PET) sheet in a self-designed reactor that included the discharge area, afterglow area and remote area. The air plasma sterilization rules in the three zones were respectively showed on the following conditions: discharge power was 60W and gas flux was...

Residual formaldehyde after low-temperature steam and formaldehyde sterilization.

The levels of formaldehyde remaining in various articles have been estimated immediately after a low-temperature steam and formaldehyde sterilizing process and after various periods of aeration. These levels have been compared with the levels of ethylene oxide remaining after exposure to an ethylene oxide sterilizing process. In rubber and polythene and a plastic, formaldehyde levels are low an...
