Staph DNA Extraction

I am looking into the ways to lyse/extract DNA from gram + cells. As far 
as I can tell, the Promega Wizardprep kit is simple do to and the 
extraction for G+ is the addition of lysozyme *(10mg/ml) @ 60 uL in a 
300 uL extraction. Then incubate for 30-60 minutes @ 37C. If you are 
having trouble lysing the staph, you can also add lysostaphin @ the same 
concentration as the lysozyme (and in concert with it). This should lyse 
almost any Staph cell.

That's what I could find out.
