[Action of dehydration on the survival, morphology and ultrastructure of the conidia of air-borne and culture collection strains of Aspergillus niger and Penicillium chrysogenum].
The effect of dehydration on the morphology and fine structure of conidia was studied with the atmospheric and collection strains of Aspergillus niger and Penicillium chrysogenum. Dehydration did not cause changes in the structure of most conidia. However, destructive changes in the conidial wall and membrane were found in some conidia. The cytological changes of conidia were either reversible or irreversible, which determined their survival rate during dehydration.
