What do you want to do with this DNA. If you need it in whole chromosomes, then you need to embed cells in agarose and digest them in-place. If you just need DNA for sequencing, library construction, or PCR, then any normal genomic prep will work fine. I've had a lot of success with the Zymed 96 well plate format preps, but also with the Sambrook CTAB protocol.
I have inserted a gene into the bacterial genome and want to find out the insertion site. So I need to extract the genomic DNA, digest it with a R.E, ligate the fragments and sequence them. In this case, any normal genomic prep will work?
