J9 Era
Increasingly stringent regulations for drinking water quality have stimulated the application of ultrafiltration to water treatment. In addition to removing particulate materials from water (including microorganisms, bacteria and viruses), the use of membrane treatment also meets purification requirements. However, irreversible fouling curtails the economic viability of such a process. Experime...
متن کاملVirucidal Activity of 3-Propiolactone Vapor
The bactericidal activity of 3-propiolactone (BPL) vapor was first reported by Hoffman and Warshowsky (1958). Although this chemical has shown promise in our laboratories as a very useful gaseous disinfectanit for rooms and buildings, the lack of information on the virucidal activity of BPL vapor has been a deterrent in the use of the chemical to decontaminate virology laboratories or buildings...
متن کاملEffect of -propiolactone on Sendai virus.
The biological properties (infectivity, hemagglutination, hemolysis, cell fusion, neuraminidase) of Sendai virus were dissociated on the basis of sensitivity to beta-propiolactone, by freeze-thawing, by heating at different temperatures, and by adsorption-elution with formalinized chicken erythrocytes. Possible mechanisms whereby beta-propiolactone selectively destroys viral infectivity are dis...
متن کاملSynthesis and Biodegradation of Poly(l-lactide-co-β-propiolactone)
Although the copolymerizations of l-lactide (LA) with seven- or six-membered ring lactones have been extensively studied, the copolymerizations of LA with four-membered ring lactones have scarcely been reported. In this work, we studied the copolymerization of LA with β-propiolactone (PL) and the properties of the obtained copolymers. The copolymerization of LA with PL was carried out using tri...
متن کاملBeta - Propiolactone Vapor as a Disinfectant 1
Despite recently revived interest in gaseous disinfection or sterilization, only two compounds, formaldehyde and ethylene oxide, have been used to any great extent for this purpose. As discussed by Phillips (1957) in a review of gaseous sterilization, several other compounds have been mentioned in the literature as possessing bactericidal properties in the vapor state but have been put to littl...
