α-Amylase of Bacillus subtilis was remarkably stabilized against pressure inactivation by calcium ion (in most of experiments, an enzyme solution containing 10^<-2> M calcium ion was used). After releasing the pressure, partially or completely pressure-inactivated enzyme was not observed to regain activity under atmospheric pressure; however, the activity was recovered to a considerable extent by recompression at a moderate pressure. A prssure of about 3000 kg per square centimeter (above this pressure the extent of reactivation gradually decreased because of competing pressure inactivation), a pH of about 7.5, a temperature of about 30°, and high concentration of enzyme were optimal for the recovery. Reactivation was almost in dependent of ionic strength.
