We studied the charge recombination characteristics of Photosystem II (PSII) redox
components in whole cells of the chlorophyll (Chl) d-dominated cyanobacterium,
Acaryochloris marina, by flash-induced chlorophyll fluorescence and thermoluminescence
measurements. Flash-induced chlorophyll fluorescence decay was retarded in the μs and
ms time ranges and accelerated in the s time range in Acaryochloris marina relative to that in
the Chl a-containing cyanobacterium, Synechocystis PCC 6803. In the presence of 3-(3, 4 …

Charge recombination characteristics in Photosystem II were studied in whole cells of the
chlorophyll d-dominated cyanobacterium, Acaryochloris marina. Thermoluminescence
intensity is enhanced 2.5-fold per photosystem II center in Acaryochloris, as compared to the
chlorophyll a containing cyanobacterium, Synechocystis 6803. Flash induced chlorophyll
fluorescence is retarded or accelerated slightly in the absence or presence of the QB site
inhibitor, DCMU, respectively, in Acaryochloris. Mild reduction retarded fluorescence …
