You can use Zymolyase alone.  It eats up different 
sugar  linkages than Novozyme so is rather less efficient 
than the mix.

Also, you can clean up the Novozyme a bit, by doing a sulfate cut
on it.  I've never done this myself so I don't remember where it
comes down, although I do remember that it makes a 
difference with respect to proteases.  I'll try to track  down
the conditions  and post it to the newsgroup.
