hmm. 131 for 2 hours and still survived but couldn't reproduce. ok. wow. hot bacteria. where's paris hilton?
i never really knew about bacteria surviving boiling water. now, if i were asked to sterilize water for somebody - i'd pressure cook it. carbon filters are supposed to strain out a lot of things. can you strain bacteria, though?
