“…under different monochromatic light wavelengths indicated that the biomass and lipid productivity followed these same photon energetics trend [85]. In addition, blue light deficient conditions may disrupt microalgal metabolism since blue light is involved in gene transcription regulation and enzyme activation [86]. Thus, 5% AD effluent was found to be the optimum dose since it provided sufficient amount of nutrients but did not lead to energy-deprivation.…”

“…The significantly lower carbohydrate content of this alga under blue light can be explained by the fact that blue light is responsible for the enhanced production and activity of respiratory enzymes in plants and microalgae [25,44]. An increase in the concentration and activity of these enzymes is proportional to the rate of catabolism of carbohydrates, hence leading carbohydrate reduction [25,44].…”

“…Blue light is an environmental signal activating or stimulating a large number of processes in algal and plant cells. Among the most important blue light-regulated phenomena are phototropism (Dennison 1979), stomatal opening (Zeiger 1983), respiration (Kowallik 1982), enzyme activation (Ruyters 1984), gene expression (Short and Briggs 1994), chlorophyll biosynthesis (Matters and Beale 1995), and chloro-plast differentiation (Buschmann et al 1978) and orientation (Haupt 1983). Some blue light-induced processes involve translocation of ions across membranes for the creation of H^ gradients or membrane potentials, induction of changes in turgor, or for nutritional purposes.…”

Blue light is one of the most important environmental signals regulating monovalent anion transport in plant cells. In the unicellular freshwater chlorophyte Monoraphidium braunii, blue light is essential for the activation of HCO3−, NO3−, NO22 and Cl− transport systems. These anions are taken up when blue light is present but the uptake ceases when this radiation is suppressed, indicating that blue light is a switch signal for the monovalent anion transport system(s) of this alga. Similar results have been obtained in other green algae and higher plants. The action spectra for the uptake of NO3− and Cl− in M. braunii are very similar and resemble the absorption spectra of flavins or a combination of flavins and pterins. It is proposed that both anions share the same transport system(s). The uptake of monovalent anions consists of a cotransport with H+, thus producing alkalinization of the external medium. The time between the onset of blue light and the beginning of alkalinization can be as short as 2 s. Taken together, the results suggest that the photoreceptor mediating the blue light activation of monovalent anion uptake in this green alga is a plasma membrane‐bound flavoprotein.
