SEATTLE — A recent University of Michigan
study has demonstrated that steam vapor rapidly and effectively destroys microbial biofilms, according to a press release.
Chuanwu Xi, PhD, assistant professor in the Department of Environmental Health
at the University of Michigan, and his research team found that treated steam from a novel steam disinfection system utilizing Accelerated Nano Crystal Sanitation
) technology rapidly kills highly resistant biofilms with greater than 99.95 percent killing efficiency in a three-second treatment and to a non-detectable level in a less than 10-second treatment, the release stated.
"Scientific studies have found that biofilms can be up to 1,000 times more resistant to biocide inactivation than are suspended microbes," said Dr. Xi.
"It is extremely difficult to get rid of biofilms and kill them. The efficacy of the steam vapor system is important because even strong chemical disinfectants such as bleach when allowed 20 minutes of dwell time did not achieve the same degree of kill that the steam vapor unit accomplished in three seconds," Dr. Xi added.
