That is not high enough to denature prions.

As far as pressure, my experiments showed not even a one log reduction
(and no calculable D-value) up to 65,000 psi in liquid as long as the
pressure did not drop suddenly.  So survival at a constant 65,000 psi
was no problem for my test bacteria.

Does anyone know what the psi is at the deep sea vents?  How does the
pressure there, compare to 65,000 psi?
