DNA from lysogenic phage

[Michael Heuzenroeder]

I'm trying to extract DNA from lysogenic phage in Salmonella. Currently
we are inducing phage with u.v light purifying by PEG precipitation, and
extracting DNA from the purified phage using standard methods. Yields
and RE digestions are poor. Does any one have any ideas how I could
possibly increase the initial yield of phage. I.e are there alternatives
to uv induction of the lytic cycle? Thanks
Michael
