Pump-during-probe Fluorometry of Phytoplankton: Group-specific Photosynthetic Characteristics from Individual Cell Analysis
ثبت نشده
چکیده
We have combined individual-cell "pump-during-probe" (PDP) measurements of chlorophyll (Chl) fluorescence induction on the time scale of 30 to 100 microseconds [1, 2] with flow cytometric (FC) characterization of each cell, to obtain population-specific photosynthetic characteristics. The results provide information about the potential quantum yield of photochemistry (I ), the fraction of functional reaction centers (f), and the functional absorption cross section for photosystem 2 (aps2).

The effect of elevated levels of phaeophytin in natural water on variable fluorescence measured from phytoplankton
Measurements of chlorophyll fluorescence are routinely used by oceanographers as well as terrestrial biologists for photosynthetic activity studies [e.g. (Bolhar-Nordenkampf and Oquist, 1993; Kolber and Falkowski, 1993)] and phytoplankton biomass estimation (Lorenzen, 1966; Falkowski and Keifer, 1985). The measurements of variable chlorophyll a fluorescence induced by actinic light are non-dest...

Under high nutrient concentrations and sufficient light conditions, large phytoplankton may display higher photosynthetic efficiency than smaller cells. This is unexpected since smaller phytoplankton, because of their higher surface to volume ratio, possess a greater ability to take up nutrients and absorb light. In order to investigate the causes of the increased photosynthetic efficiency in l...

Photosynthetic pigments in a warm core eddy of the East Australian Current were studied by In vjvo fluorometry, spectrophotometry and thin-layer chromatography. The Variosens i n sltu fluorometer gave only an approximate guide to the location and quantity of phytoplankton in the water column; spectrophotometric curve analysis revealed the presence of intact or detrital chlorophylls, and quantit...
