H.S.Olsen; P. Falholt. “The Role of Enzymes in Modern Detergency” J. Surf. Det., 1(44), 555-567 (1998) Abstract Enzymes have effectively assisted the development and improvement of modern household and industrial detergents. The major classes of detergent enzymes – proteases, lipases, amylases and
Comparison of results of ATP bioluminescence and traditional hygiene swabbing methods for the determination of surface cleanliness at a hospital kitchen. Abstract Adenosine triphosphate (ATP) bioluminescence and traditional microbiological swabbing culture methods were used for detection of surface hygiene on worktops, cutting boards
Abstract Dishcloths used in restaurants and bars (23 restaurant cloths, 14 bar cloths) were collected, and tabletops (10 restaurants) were swabbed, to determine the occurrence of bacteria. Coliforms were isolated from 89.2% of dishcloths and 70% of tabletops. Escherichia coli was isolated from 54.1%
Abstract: A four-part study assessing cleanliness in up to 113 environmental surfaces in an operating theater and a hospital ward was reported. Surfaces were assessed visually, using microbiological methods and ATP bioluminescence. Results from a preliminary random survey indicated variability in cleanliness. These results
Abstract Electrolyzed oxidizing (EO) water has been regarded as a new sanitizer in recent years. Production of EO water needs only water and salt (sodium chloride). EO water has the following advantages over other traditional cleaning agents: effective disinfection, easy operation, relatively inexpensive, and environmentally
Some 40% of commercial disinfectants used to clean surfaces are believed to be ineffective in eliminating noroviruses, a group of viruses responsible for more than half of all foodborne gastroenteritis outbreaks. According to a recent study published by Université Laval researchers in the Journal of
Abstract The presence of microorganisms on common classroom contact surfaces (fomites) was determined to identify the areas most likely to become contaminated. Six elementary classrooms were divided into control and intervention groups (cleaned daily with a quaternary ammonium wipe) and tested for heterotrophic bacteria.
Abstract After reports of increased severity of bacterial infections from community institutions, a broad spectrum of 70 surfaces was sampled for potential bacterial pathogens in the morning and afternoon of one day per week over three consecutive weeks in a large U.S. university. Surfaces included
Summary This study characterized the indoor environment of a multi-floor, multi-use, non-problem, non-complaint building through long term sampling for a variety of substances. Sampling was done for biological, chemical, and particulate pollutants. The study further assessed the effects of cleaning on indoor air quality. The
When cleaned regularly, [registered] antimicrobial copper alloy surfaces kill greater than 99.9% of (specific) bacteria within two hours, and continue to kill more than 99% of (these) bacteria even after repeated contamination. The use of a copper alloy surface is a supplement to and not
