Abstract

AbstractIn the present study, we analysed metabolite features during the dehydration–rehydration process for two Schizosaccharomyces pombe strains with different viability rate, in order to determine whether metabolite contents were affected by the presence of magnesium during cell rehydration. The qualitative changes of the intracellular metabolites of both strains were determined by comparing the metabolic profiles of cells before dehydration, after rehydration in water or magnesium solution, and after 2‐hr inoculation of cells in complete medium. Our results suggest that changes of metabolites from the methionine salvage pathway, in particular 5′‐methylthioadenosine, triggered by the increasing intracellular magnesium content may participate in the dehydration tolerance of Sp97 cells.
