La microalga Scenedesmus obliquus fue inmovilizada en esferas de Ca-alginato en dos densidades celulares del cultivo 6. Immobilization of Botryococcus braunii in alginate: Wastewater inorganic N and P removal by immobilized Chlorella vulgaris. However, in contrast to free-cell cultures, the appropriate light intensity obtained within the light limitation zone P-I curves did not cause a scenexesmus biomass production and protein content.

Both irradiances showed no significant differences on growth rates 0. The gradual proteins increase with time indicated that the growth and production of proteins began immediately after adding the beads to the culture medium, showing that the microalgae S.

Beads with high cell density showed an increase of the photosynthetic rate with a maximum of 0. This may be caused by the previous adaptation of S.

About beads of calcium alginate 2.

Use of immobilized algae for estimating bioavailable phosphorus released by zooplankton. Ammonia removal crrecimiento biomass characteristic of alginate-immobilized Scenedesmus obliquus cultures treating real wastewater.

Light limitation by the self-shading effect is one of the main causes affecting algae growth and their protein content in immobilized systems Pane et al.

Efficiency of immobilized hyperconcentrated algae for ammonium and orthophosphorus removal from wastewater. Services on Demand Article.

Scenedesmus obliquus, photosynthesis, immobilized cells protein content. Resumen La microalga Scenedesmus obliquus fue inmovilizada en esferas de Ca-alginato en dos densidades crecimienfo del cultivo 6.



The relationship between photosynthesis and light for natural assemblages of coastal marine phytoplankton. In situ measurement of microalgal growth potential in aquatic ecosystems by immobilized algae. Universidad de Antioquia; Es probable que S. Therefore, light intensities not have significant effects on the growth and protein content in beads with low cell density cultures.

For the determination of ash-free dry-weight biomass in beads, five beads in triplicate were dissolved in 5 mL of 0. The photosynthetic rates reached for high and low stocking density of immobilized S. Otros trabajos iniciales fueron los de Van Donk et al. Jeanfils and Collar reported for S.

Los trabajos de Delgadillo y Pineda constituyen los primero acercamientos con esta perspectiva. Each reactor scejedesmus operated with a beads concentration of approximately 2.

Alginate beads as synthetic inoculant carriers for the slow release of bacteria that affect plant growth. Las dos irradiancias no mostraron diferencias significativas en las tasas de crecimiento 0. Immobilization method Prior to immobilization, the stock suspension of microalgae was centrifuged at rpm for 15 min and the cell pellets were washed twice with distilled water to remove the residual nutrients that might adhere to the cell surface.

Photosynthetic rate estimation Photosynthetic rates P of immobilized cell cultures of S. Por otra parte, el hecho de que S. Alginate microbeads as inoculant carriers for plant growth-promoting bacteria. Para facilitar la solubilidad de las esferas, se agitaron vigorosamente en un Shaker rotatorio a rpm Bashan, ; Bashan et al. New York, Cambridge University Press: Universidad Jorge Tadeo Lozano; It is possible to reach high contents of chlorophyll and high photosynthetic rates for immobilized cells in alginate for species such as Chlorella sp.

Increased pigment and lipid content, lipid variety, and cell and population size of the microalgae Chlorella spp. This could be advantageous, because the cultures can work with crecimento wide range of intensity of light in tropical regions. Biological tertiary treatment of urban sceneresmus with chitosan-immobilized Phormidium.


Ten beads and stock suspensions of S. This paper describes the immobilization technique of microalgae in calcium alginate beads. Protein measurement with the Folin phenol reagent.

Dry weigh, packed cell volume and optical density.

Wastewater nutrients N and P removal by carrageenan and alginate immobilized Chlorella vulgaris. Materials and Methods Routine of culture Stock suspension of S.

However, the optimum light intensity in immobilized cultures has not been reported, as growth and content of proteins within the matrix can exist, due to light availability. Abstract The micfoalgae Scenedesmus obliquus was immobilized in Ca-alginate beads at two stocking cell densities 6. Effect of intermittent CO 2 enrichment during nutrient starvation on tertiary treatment of wastewater by alginate-immobilized Scenedesmus bicellularis.

Results and Discussion Activity of immobilized algae The photosynthetic rates reached for high and low stocking density of immobilized S. Effects of Dursban 4E and its carrier on three microalgal species during exponential and P-limited growth. Light and temperature effects on the growth rate of three freshwater algae isolated from a eutrophic lake.

Effect of immobilized microalgal bead concentrations on wastewater nutrient removal. Phycological Society of America. This suggests that the light intensity within the limitation area described in the waves P-I did not affect the growth and content of protein when low cells stocking density beads are used. Growth The growth of immobilized S.
