To clarify the lethal injury related to the inactivation ofSaccharomyces pastorianuscells by low-pressure carbon dioxide microbubble (CO2MB) treatment, surviving number, leakage of nucleic acids and proteins, fluorescence polarisation (FP) of the cell membrane, activity of alkaline phosphatase (AP), intracellular pH (pHin), mitochondrial membrane potential (MMP), cell surface hydrophobicity (CSH) and oxidative stress ofS. pastorianustreated with CO2MB at various temperatures were measured. The number of survivingS. pastorianuscells decreased below the detection limit after CO2MB treatment at temperatures of 40, 45 and 50 ℃, inducing a 2-log reduction at 35 ℃. TheS. pastorianuscells treated with CO2MB at temperatures above 40 ℃ showed an increase in FP and leakage of nucleic acids and proteins. The AP inS. pastorianuscells treated with CO2MB at a temperature of 35 ℃ was also activated but inactivated at temperatures above 40 ℃. Furthermore, the decrease in pHinand MMP and the increase in CSH ofS. pastorianuswere caused by CO2MB treatment at temperatures above 35 ℃. Oxidative stress inS. pastorianuscells was also increased by CO2MB treatment without warming but decreased at temperatures above 35 ℃. Our results lead us to infer that the type of cell injury inS. pastorianusinduced by CO2MB treatment differed from that caused by the treatment temperature and that the lethal injury was enzyme inactivation.
