Re: Microorganisms surviving for 5300 years

[Guest guest]

Well, I guess this answers the question of storage halflives. So it's probably

more an issue of the denaturing of mycotoxins vs. spore viability.

Definitely! Archaelogists have opened Egyptian tombs that were

hermetically sealed and had air pressure differential which lit up

with fungal growth as soon as they were opened.

Fungi still viable!

The " Curse of the Pharoahs " can still kill today.

I read recently about a researcher who dropped with Aspergillosis

after examining Nefertiris starry vault.

But the properties of sporulation require reinforcement of reserves

for such long periods of stasis, spore plumes are fragile according

to what I read.
