Stationary delayed fluorescence (DF) of chlorophyll in isolated membrane preparations from thermophilic cyanobacterium Synechococcus elongatus was investigated as a function of temperature. Two peaks at different temperatures were observed. The low-temperature peak (54-60 degrees C) coincided with t...
