What has changed, in fact, is the fact that the person no longer has an
immune system that is capable of eliminating these bacteria because, of course,
he is now dead.  Similarly, there is a host of E. Coli and other bacteria
that live in our GI tract that will continue to function once we have
expired.  Perhaps it is these bacteria that are producing, amongst other
things, carbon dioxide, methane, etc.  thus the bloating.
