Why pasteurize for an hour?

Just curious as to why straw and such are pasteurized for an hour? Ive read that 160 only has to be reached for seconds to pasteurize, though i understand the idea of trying to make sure all the substrate is the right temp. Are there other reasons too?

well for one as you stated
the temperature has to be 140+ f throughout the straw not just the surface, moisture is absorbed in this time.
also RR says the processes is beneficial throughout the 60-90minutre range at 140-160f.
so I'm assuming pasturization works over that period of time.
for the same reason you spend more than 5 seconds washing your hands... assuming you do.

Pasteurization of substrates doesn't take a few seconds. It takes an hour. The idea is to kill all of the mold spores, and some of the bacteria. The surviving bacteria keep the substrate 'alive', thus reducing the chances of molds forming. A few bacteria in a substrate will also improve fruiting, and some species simply will not fruit on a sterile substrate. RR

okay, i just read on wikipedia that milk is pasteurized for a few seconds, but i'm sure they are worried about bacteria and not mold spores. Thanks.

milk pasteurization and mycology pasteurization are two different things.
We as humans can live in filthy as hell environments and not get sick, we can eat raw meat, drink milk straight from a cow and be fine.
The idea of pasteurization for straw/poo is to kill off mold and keep beneficial bacteria as RR said.
Pasteurization for milk is at a very hot temperature and it is to quickly kill off bacteria mostly to improve the fridgerated life of the milk.
