Abstract
The mechanism of inactivation of freeze-dried Lactobacillus bulgaricus during storage in maltodextrin under controlled humidity was investig ated. Evidence is presented supporting the hypothesis that membrane da mage occurs during storage. A study ore the lipid composition of the c ells by gas chromatography showed a decrease in the unsaturated and sa turated fatty acid content of the cell. Further evidence indicating me mbrane damage includes a decrease in membrane bound proton-translocati ng ATPase activity.
