Influence of Molecular Oxygen on the Chlorophyll Fluorescence Decay of Green Algae
نویسندگان
چکیده
Molecular oxygen can act as a collisional quencher of the singlet excited state of chloro phyll a. This effect is well described for chlorophyll a in various solvents but not for chloro phyll a in the antenna complexes of photosynthetic organisms. We studied the chlorophyll fluorescence decay of Chlorella vulgaris cells under different oxygen concentrations but did not find any evidence for quenching by oxygen.

pH control of the chlorophyll a fluorescence in algae.
The pH of the suspension medium was found to have a remarkable influence on the "slow" (min) time course of Chlorophyll a fluorescence yield in the green alga Chlorella pyrenoidosa and in the blue-green alga Anacys t i s nidulans. In Chlorella, the decay of fluorescence yield, in the Ito 5-rain region, is strongly retarded at alkaline pH ; this decay rate shows an optimum at pH 67. In Anacystis...
متن کاملMode-locked lasers: measurements of very fast radiative decay in fluorescent systems.
A mnode-locked laser was used to measure fluorescence decay down to 80 picoseconds. Measurements on the fluorescence of methylene blue quenchled with potassium iodide demonstrate the effectiveness of the method. Fluorescence decay times of chlorophyll b (3.87 +/- 0.05 nianoseconds) and c-phycocyanin (1.14 +/- 0.01 nanoseconds) in vitro and chlorophyll a in the green alga Chlorella pyrenoidosa (...
متن کاملSinglet-triplet annihilation in single LHCII complexes.
In light harvesting complex II (LHCII) of higher plants and green algae, carotenoids (Cars) have an important function to quench chlorophyll (Chl) triplet states and therefore avoid the production of harmful singlet oxygen. The resulting Car triplet states lead to a non-linear self-quenching mechanism called singlet-triplet (S-T) annihilation that strongly depends on the excitation density. In ...
متن کاملQuantitative (Chlorophyll-a) and qualitative (species composition) seasonal fluctuations of phytoplankton in Lavan coastal waters (North of the Persian Gulf)
Phytoplankton species composition as well as amount of Chlorophyll-a and their relation to physico-chemical parameters were studied. The samples were collected monthly from October 1996 until September 1997 in two stations, i.e. Lavan and Douberkeh coastal waters. In this study, 65 phytoplankton species related to 3 groups of diatoms, dinoflagellats and Blue-Green Algae (24 genus and 44 species...
متن کاملA taxonomic study of blue-green algae based on morphological, physiological and molecular characterization in Yazd province terrestrial ecosystems (Iran)
Based on the limited resources available to algal flora in Yazd province in the center of Iran, cultivation, purification and identification of soil algae from seven sites was performed in summer 2013. The soil samples were processed for analysis of Cd, Pb contents. The present paper attempts to analyze survey of soil blue-green algal identification in different types of stations, using morphol...
