recent book about bacterial spores?

[Chris=Michiels%LMM%AGR at agr.kuleuven.ac.be]

I am looking for a (d)(r)ecent book dealing with several aspects of bacterial spores,
or sporulating bacteria: sporulation, germination, resistance, inactivation, genetics,
physiology...
Thanks for your suggestions.
