A correlation was found between the rate of cell death induced by heat and the GSH content of Synechocystis PCC 6803: cells accumulating GSH above the control level were more tolerant to heat than the control cells, and those containing a lower concentration of GSH were more sensitive. Lethal heating caused a decrease of GSH content, and a rapid intracellular oxidation in cells containing the decreased amount of GSH.
