I'm not a learned head, but biofiltration is an interest of mine. Optimal
growth occurs in a range from 22-26 oC. One group isolated an ammonia
oxidizing bacteria that grew at -5 oC. Nitrifiers can acclimate to
temperatures out of optimal range if the change is slow, but surely
metabolism slows at lower temps.
