摘要：

Chlorella fusca was subjected to evaporative dehydration under air humidity of 72%. Ca2+ pretreated cultures lost water as rapidly as untreated cultures. Nevertheless, an ameliorative effect of Ca2+ pretreatment in droughted cells was found as membrane stability index was improved and K+ leakage was reduced. In addition, higher chlorophyll content and stability was observed. These parameters enabled droughted cells to recommence growth upon rewatering. Thus Ca2+ might increase survival of C. fusca cells subjected to drought through membrane stabilization.
