Is zymoliase worth for my purpose and where can I find it cheap?

>hcano at alboran.ualm.es>There is a relatively inexpensive device called a "Bead Beater" made by
a company called Biospec in Oklahoma. We have had excellent results
breaking many difficult gram positives and yeast with the device. It uses
shearing action, so it cannot be used to isolate DNA, but it appears to
work well for many enzymes. Comes with a cooling jacket that you fill with
ice and water. Email me if you need details.
