Metabolic inhibitors were added to a culture medium inoculated with thermally stressed Vibrio parahaemolyticus to obtain information pertaining to biosynthetic processes required for recovery from heat damage. Ribonucleic acid and protein syntheses, in addition to membrane repair, were required during recovery of injured cells. Neither nucleic acid nor Mg/sup 2 +/ leakage was noted to occur during the time cells were subjected to heat stress. Studies revealed that Mg/sup 2 +/ was apparently taken up by cells of V. parahaemolyticus during the first 30 min after thermal treatment, indicating a possible increased requirement for Mg/sup 2 +/ for membrane and/or ribosome stability and repair.
