Influence of carbon nanotubes on chlorophyll fluorescence parameters of green algae Chlamydomonas reinhardtii

It has been shown that carbon nanotubes are capable of decreasing the development speed of Chlamydomonas reinhardtii algae culture and significantly changing the parameters of chlorophyll fluorescence that characterize the prime processes of light energy storage throughout photosynthesis. The quantum yield reduction of photochemical light energy transformation during photosynthesis and the relative speed of noncycle electron transfer calculated using the fluorescence parameters have been observed. The inhibition of the electrochemical proton gradient involved in ATP synthesis has been determined using delayed fluorescence. A conclusion on the prospects of implementing highly sensitive fluorescent methods for evaluating the toxic effect of modern nonmaterials on water objects is made.
