The photosynthetic variables obtained crecimento immobilized S. Analysis of the cellular density and proteins Reactors consisted of cylindrical transparent polyethylene terephthalate PTFE vessels 3 L capacity each containing 2. 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.
Partitioning of transfer and carboxylation components of intracellular resistance to photosynthetic CO df fixation: Factors affecting the growth characteristics of alginate-entrapped Chlorella. 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.
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.

The se activity associated to the high content of chlorophyll is related to the limitation of the light in the beads. Effect of intermittent CO 2 enrichment during nutrient starvation on tertiary treatment of wastewater by alginate-immobilized Scenedesmus bicellularis.

Reactors consisted of cylindrical transparent polyethylene terephthalate PTFE vessels 3 L capacity ed containing 2. It is possible to reach high contents of chlorophyll and high photosynthetic rates for immobilized cells in alginate for species such as Chlorella sp.
Ammonia removal and biomass characteristic of alginate-immobilized Scenedesmus obliquus cultures treating real wastewater. A similar trend was reported by Bartual et al. Efficiency of immobilized hyperconcentrated algae for ammonium and orthophosphorus removal from wastewater.
Each reactor was operated with a beads concentration of approximately 2. Light is an important variable in the design and operation scenedeskus microalgae culture systems and bioreactors Andersen, The stability of beads, the kinetics of growth and the concentrations of microalgae inside the beads were determined.

In the analysis of P-I curves it is important to take into account the conditions of the culture, such as high cell density cultures, which may cause considerable light attenuation. Statistical analyses The photosynthetic rate data in the experiments with two cellular densities in alginate beads were analyzed by analysis of variance ANOVA. Light and temperature effects on the growth rate of three freshwater algae isolated from a eutrophic lake.
Universidad de Antioquia; For the determination of ash-free dry-weight biomass in beads, five beads in triplicate were dissolved in 5 mL of 0.
En un estudio sobre la ultraestructura de las esferas de alginato Lebsky et al.
Características fotosintéticas y crecimiento de Scenedesmus obliquus inmovilizada en alginato
Two types of beads were prepared, one with stocking cell density of 6. Therefore, it is important to determine and use optimized culture crecijiento for the correct interpretation of the experimental results.
Nitrite uptake by Chlamydomonas reinhardtii cells immobilized in calcium alginate. Abstract The micfoalgae Scenedesmus obliquus was immobilized in Ca-alginate beads at two stocking cell densities 6.
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.
Results and Discussion Activity of immobilized algae The photosynthetic rates reached for high and low stocking density of immobilized S. The relationship between photosynthesis and light for natural assemblages of coastal marine phytoplankton.
Los trabajos de Delgadillo y Pineda constituyen los primero acercamientos con esta perspectiva. La microalga Scenedesmus obliquus crecijiento inmovilizada en esferas de Ca-alginato en dos densidades celulares del cultivo 6.
