Well, of course there's as many ways to do this as there are people in the
lab doing it.  We've have good luck with 0.5M NaOH and about 30 seconds of
microwaving at 600-700 watts (usually close to full power).  Some people
like to soak the filters in saline before microwaving and then treat with
NaOH.  Look at Datta et al., Appl. Environ. Microbiol. 53:2256 (1987).
Good Luck,  -Walt Hill
