I am doing a lab to teat the
effectiveness of anitbacterial cleaners in my biology class. I was wondering if
you know which ingredient of antibacterial sprays is most effective?
How does it work to kill the bacteria?
In the Virtual Museum of Bacteria,
www.bacteriamuseum.org you will find a display about
food safety, at
In this page there is a link to an article from
Scientific American dealing with antibacterial agents
in sprays and cleansers.
It depends on the bacteria you use. Different organisms have different
sensitivities to the same disinfectants. If you are having them test them on
their own hand bacteria, not all of the bacteria will be killed. (You can't
sterilize your skin) In fact you may not see much of a difference at all!
You might try different types of antiseptics/disinfectants on the same
bacteria, or different strengths of the same antiseptic on the same bacteria.
