LH100 + TA061 temperature

Will this two Survive 131F (55C) ?

Hi.

Both of these cultures contain thermophiles so they should survive those temps, although I think they are at the top of their ranges so may well be getting a bit stressed.

Depends on time as well as temperature. Why are you asking?

[tal_d1]

I am asking because the Parmesan recipe instruct to hit to 55C and live it at
this temp for 1 hour and the book "Mastering Artisan Cheese" say that LH100 live up
to 52C.

We prepare a culture by heat treating whey from the cheese just made.

We do this by placing the whey in a hot water bath and quickly heating up to 62 C, then placing in a cold water bath and quickly cooling it down to 40 C

This culture consists of bacteria pretty much the same as your cultures listed. They will survive. Everything else will die (for the most part)
