Sterilization of microorganisms with supercritical carbon dioxide. [PDF]

Agricultural and Biological Chemistry, 1987
The sterilizing effect of supercritical carbon dioxide (SC-C02) is described as compared with gaseous C02(G-C02) and liquid C02(L-C02). Baker’s yeast, Escherichia coli, Staphylococcus aureus and conidia of Aspergillus niger were sterilized by treating with SC-C02 at 200 atm and 35°C when the water content of each microorganism was 70 ~ 90%.
