>I'd begin by looking at the recent ASM publication "Methods for General and
Molecular Bacteriology." Chapter 12 is devoted to culture preservation,
and Table 1 (p. 281) seems to indicate that freeze-drying (lyophilization)
is the method of choice for a broad range of species, both facultative and
obligate anaerobes, gram-positive and gram-negative.
I've only just glanced at this, but I think it may be useful to you. There
are also several references at the end of the chapter for further reading.
Good luck!
