[compost_tea] New research announcement on using ultrasound
I know
this is going the wrong way on bacterial growth, but this could be used for
disinfection of plastic containers, as well as the big ramifications on other
bacterial clean up.
The
link below takes you to a news story on how a firm has discovered that
ultrasound can be used for 30 seconds or so to kill Bt, and most likely anthrax
bacteria. Here's a quote:
"High-power ultrasound, currently used for cell
disruption, particle size reduction, welding and vaporization, has been shown to
be 99.99 percent effective in killing bacterial spores after only 30 seconds of
non contact exposure in experiments conducted by researchers at Penn State and
Ultran Labs, Boalsburg, Pa."
"Hoover explains that the team used Bt spores in their
experiments rather than the deadly anthrax spores found to contaminate mail last
year. Bt, bacillus thuringiensis, is a common commercial insecticide and is also
a close cousin of the anthrax bacillus. "Bacillus anthracis and bacillus
thuringiensis are very close relatives," she adds. "They differ by only a few
genes on their plasmids that encode different toxins. If you remove those
plasmids, Bt cannot be distinguished from B. anthracis and therefore can serve
as a safe model for testing." "
One of
the first applications will be on cleaning mail in the Post Office. I
thought "what about cleaning compost tea tanks"?
If
this technique is duplicated by other scientists and technologists (this list?)
then the technique will have very wide application for anyone in the hort
business.
