Shit, you are right.
What were they called in the common tongue, water bears or something? Tardigrades I believe was their scientific name.
Not sure if "micro animals" and microbes are in the same category but tardigrades can, if memory serves, even survive vacuum, extreme temperatures for sure.
Makes sense that there are at least some types of microbes that can compete with the tardigrade in terms of survivalism.
So basically, to get back to OP's question, he shouldn't worry too much about it. While freezing solid, even that wouldn't "kill" the soil completely, just part of the microherd would be negatively affected?
