Try a Chelex extraction protocol. There are several protocols available online.  It's cheap and easy if you don't necessarily need high quality DNA. Basically you pick the colony, put in ~100 ul of chelex suspension, then perform a series of vortex-spin-heat-freeze cycles. The DNA is good enough for PCR.

Pick clones using a pipet tip and pipet up and down into 50 ul lysis buffer (TE with 0.1% Tween 20).  Boil for 10 min and spin for 2 min.  DNA is in supernatant.  Good luck!

Is according to straing bacteria as G+ or G-. The first must be use the lysosyme and for the second there a simple protocole without enzym. You find in attached thesis the simple protocole. Good luck my friend.
