1.    Treat them with chloroform, though you might loose some enzyme

2.    Put them straight into liquid nitrogen, and grind them in a mortar and

3.    Use a sonic probe ....

The few times I've done this type of work I've used 1 & 3.

Number 2 is a guess, though it might be difficult to fracture bacterial
cells this way, though others will probably give you better methods. Pd.
