EFFECTS OF SALT AND IRRADIANCE STRESS ON PHOTOSYNTHETIC PIGMENTS AND PROTEINS IN DUNALIELLA SALINA TEODORESCO
The aim of this study was to examine the effects of salinity and light intensity on the chlorophylls, ?-carotene and protein contents in Dunaliella salina Teod. The algae were grown in inorganic medium containing 0, 0.9, 1.8 (control), 2.6 and 3.5 M NaCl under three illumination regimens [4500 (control), 9000 and 11000 Lux]. The results showed that most electrophoresis protein bands were separa...
متن کاملPhotosynthetic Pigments in Diatoms
Photosynthetic pigments are bioactive compounds of great importance for the food, cosmetic, and pharmaceutical industries. They are not only responsible for capturing solar energy to carry out photosynthesis, but also play a role in photoprotective processes and display antioxidant activity, all of which contribute to effective biomass and oxygen production. Diatoms are organisms of a distinct ...
متن کاملLight absorption by phytoplankton, photosynthetic pigments and detritus in the California Current System
Pigment-specific absorption bq total particulatea. detritus and phytoplankton was measured throughout the euphotic zone at > 275 stations on three cruises off California in late IYY 1 and early 1992. A new spectral Ruoresccncc method for assessing photosynthetically active absorption in natural samples was developed and applied. Spatial variability in specific absorption coefficients at the mes...
متن کاملDevelopment of sensitized solar cells by photosynthetic pigments
Background Grätzel solar cell, also known as dye-sensitized solar cell (DSSC), is a dye-sensitized nanocrystalline photovoltaic cell of TiO2 (titanium dioxide). It has a surface of nanoporous TiO2, a semiconductor of a wide bandgap. The basic principle is to transform light energy into electrical energy. When a dye molecule absorbs light, an electron is replaced by an excited state, and this dy...
