Microbiological aspects of ethylene oxide sterilization. IV. Influence of thickness of polyethylene film on the sporicidal activity of ethylene oxide.
Spores of Bacillus subtilis var. niger, dried on nonhygroscopic and hygroscopic surfaces, were enclosed in one of four thicknesses of low-density polyethylene film (2, 4, 6, and 20 mils). The surfaces were then placed in a specially designed thermochemical death rate apparatus and exposed to an ethylene oxide concentration of 600 mg/liter (at 54.4 C) and 50% relative humidity. Survival data, in...

متن کاملImmunologic Studies with Ethylene Oxide-treated Human Serum
The antigenicity of an ethylene oxide-treated human serum in humans has been studied. The immune response to the material had many of the characteristics of a delayed cellular skin reaction. Even after repeated immunizations by intradermal skin testing over a period of 1(1/2) years, no detectable antibody could be found in the sera. The antigenicity has been shown to be associated with drastic ...
متن کاملEffect of Moisture on Ethylene Oxide Sterilization.
Bacterial cells dehydrated beyond a critical point no longer react uniformly to ethylene oxide sterilization. The percentage of cells resistant to the lethal effect of ethylene oxide after desiccation is often as small as 0.1 to 0.001%. However, 5% resistant cells were observed with one type of microorganism dried in broth. The presence of organic matter increases the percentage of cells that b...
متن کاملNitric oxide as a potent fumigant for postharvest pest control.
There is a great demand for safe and effective alternative fumigants to replace methyl bromide and other toxic fumigants for postharvest pest control. Nitric oxide, a common signal molecule in biological systems, was found to be effective and safe to control insects under ultralow oxygen conditions. Four insect species including western flower thrips, Frankliniella occidentalis (Pergande) (Thys...
