[Relation of growth and decay kinetics of the microwave photoconductivity signal of Chlorella to its culture state].

Signals of microwave photoconductivity (MPC) of Chlorella cells in various physiological states and at various illumination conditions have been studied. It was shown that cells of high photosynthetic activity and unruptured electron transfer system give MPC signals of the type I (nonmonotonic rise and decay kinetics). A decrease of photosynthetic activity leads to the appearance of MPC signals of the type II (monotonic rise and decay kinetics).
