Role of trehalose in the spores of Streptomyces

Year: 1986

Type: article

Abstract: Dormant spores of Streptomyces antibioticus contain large amounts of trehalose (11–12% of dry weight) and can be subjected to a dehydration treatment without a significant loss of viability. Loss of dehydration resistance coincided with a decrease in the trehalose level of the spores, under different conditions of incubation. The viability of dehydration-sensitive cells was enhanced by the presence of exogenous trehalose during dehydration. The morphology and functional activity of isolated membranes of S. antibioticus can be retained when dehydrated in the presence of trehalose. It is suggested that, in dormant spores of S. antibioticus, trehalose may serve to protect cellular components during dehydration by acting as a substitute for water.
