Mutant LF-1 of the green alga Scenedesmus obliquus has been described by Metz and co-workers (Metz, J. G., Pakrasi, H., Seibert, M., and Arntzen, C. J. (1986) FEBS Lett. 205, 269-274) to be inactive for light-driven oxygen evolution, despite a functional Photo-system II reaction center. A polypeptide, D1, implicated in the ligation of the primary photoreactants of photosystem II, was shown to m...

Two outdoor open thin-layer cascade systems operated as batch cultures with the alga Scenedesmus obliquus were used to compare the productivity and photosynthetic acclimations in control and CO2 supplemented cultures in relation with the outdoor light irradiance. We found that the culture productivity was limited by CO2 availability. In the CO2 supplemented culture, we obtained a productivity o...

This article found that 123 species and of microscopic algae, belonging to 4 divisions, 9 classes, 19 orders, 25 families, 32 genera, are distributed in the algal flora Dengizkol reservoir. When analyzing algae natural reservoir contour sections, it was number is high areas where water flows into lake, low remote from inflow water. In particular, 114 phytoplankton were 1st circuit collector, 10...

Five microalgae strains, namely Isochrysis galbana, Microchloropsis gaditana, Scenedesmus obliquus, Nannochloropsis oculata and Tetraselmis suecica, were selected as potential candidates for polyunsaturated fatty acids’ production, evaluating biomass productivity their capacity to accumulate high lipid contents under different trophic modes. Microalgae strains cultivated in the presence of 1% g...
