["Burning" of troughs in the low-temperature absorption spectra of a strain of Chlamydomonas reinhardii enriched by P700].
Spectral and photochemical parameters were described of the mutant strain of Chlamydomonas reinhardii 516--3a, in which the ratio chlorophyll a/P700 is about 20. Experiments were carried out with this strain for investigating earlier observed for Chlorella effect of burning out of deeps in absorption spectra at 4.2K resulting from irradiation with monochromatic light of the wavelength 698 nm. Arguments are presented in favour of the assumption that phototransformation of P700 is responsible for the formation of deeps. It has been found from the width of the deeps that the lifetime of the excited states of the centres responsible for the formation of deeps is between 16 ps and 65 ps.
