Sterilization of Microorganisms with Supercritical Carbon Dioxide
Open accessAbstract
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%. However, dry cells with a water content of 2 ~ 10% could not be sterilized under the same conditions. No sterilizing effect from SC-C02 on endospores of Bacillus subtilis and B. s tear other mophilus was observed. G-C02 and L-C02 produced no sterilizing effect against both wet and dry baker’s yeast cells, while wet E. coli cells were sterilized with G-C02. Although dry conidia of A. niger could not be sterilized with SC-C02 alone, the addition of ethanol or acetic acid to SC-C02 made it possible to sterilize these. Without any decrease in their enzymatic activities, E. coli and baker’s yeast in α-amylase and lipase preparations were sterilized with SC-C02.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
