You have to time it with the immune system. If it is too active it
will attack the bacteria and you won't get much use from them. On the
other hand, infusing them when the patient is cooling might mean they
have a too short time window to produce cryoprotectants before they
freeze too.

In my opinion the best solution would be to add genes for
cryoprotectants connected to a hormone promotor from some insect
either prenatally or through gene therapy during adulthood, and then
activate the cryoprotectant production when it becomes necessary. Why
involve bacteria when there are trillions of cells?
