Changes in light intensity would result in variations in the pigment composition, concentrations of the components of electron transport chains, carboxylic enzyme activities, photosynthetic rates, dark respiration rates and biochemical composition Bartual et al. Handbook of Phycological Methods. Otros trabajos iniciales fueron los de Van Donk et al.

Por otra parte, el hecho de que S. Both irradiances showed that only around 5. Bajo condiciones de laboratorio Twist et al. A topic of interest is the utilization of algal biomass, but this depends on its biochemical composition, which is scenedesmmus by the nutrients concentration and culture medium composition, as well as, temperature, light intensity and wavelength.

I curve indicated the specific irradiance that allows a maximum photosynthetic rate without reaching photo-inhibition. Every 6 h the numbers of cells in the beads were counted with a particle analyzer model Beckman Coulter Multisizer 3, after dissolving one bead in 5 mL of 0. This cellular concentration was higher than that obtained at UE m -2 s -1 from 3. Resumen La microalga Scenedesmus obliquus fue inmovilizada en esferas de Ca-alginato en dos densidades celulares del cultivo 6.


Effect of irradiance on growth, photosynthesis, pigment content and nutrient consumption in dense cultures of Rhodomonas salina Wislouch Cryptophyceae. Growth The growth of immobilized S.


Both growth rates were lower than those reported for S. Effect of intermittent CO 2 enrichment during nutrient starvation on tertiary treatment of wastewater by alginate-immobilized Scenedesmus bicellularis. The relationship between photosynthesis and light for natural assemblages of coastal marine phytoplankton. Other factors such as CO 2 and temperature should be taken into consideration.

Características fotosintéticas y crecimiento de Scenedesmus obliquus inmovilizada en alginato

However, there are few studies about the photosynthetic characteristics of S. In order to increase protein content, other factors such as CO 2 level, temperature and pH should be tested if the aim is to use the biomass as food supplement.

A novel in-situ biomonitor using alginate immobilised algae Scenedesmus subspicatus for the assessment of eutrophication in flowing surface waters.

A similar trend was reported by Bartual et al. Under the light intensities selected in the present study there were no significant effects of light intensities on the growth and protein content of S.


Results and Discussion Activity of immobilized algae The photosynthetic rates reached for high and low stocking density of immobilized S. Microalgae growth-promoting bacteria as ”helpers” for microalgae: The micfoalgae Scenedesmus obliquus was immobilized in Ca-alginate beads at two stocking cell densities 6. This scenedsmus be caused by the previous adaptation of S. Review of practical aspects.

Photosynthetic rates P of immobilized cell cultures of S. Alginate microbeads as inoculant carriers for plant growth-promoting bacteria. Consecuentemente, sus tasas de crecimiento fueron relativamente altas en todos los tratamientos.

Immobilized microalgae for removing pollutants: Effects of Dursban 4E and its carrier on three microalgal species during exponential and P-limited growth.

A valid consideration is that if nutrients are not limiting and physiological conditions are optimal, then the photosynthetic activity is controlled only by light intensity. Mendoza-Espinosa 2M. Photosynthetic characteristics and growth of alginate-immobilized Scenedesmus obliquus.
