I curve indicated the specific irradiance that allows a maximum photosynthetic rate without reaching photo-inhibition.

V, Venkataraman, and P. Photosynthetic rate estimation Photosynthetic rates P of immobilized cell cultures of S.

Photosynthetic rates P of immobilized cell cultures of S. Both irradiances showed no significant differences on growth rates 0. Effects of different methods of processing on the protein efficiency ratio of the green alga Scenedesmus acutus.

For the determination of ash-free dry-weight biomass in beads, five beads in triplicate were dissolved in 5 mL of 0. 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.

Reactors consisted of cylindrical transparent polyethylene terephthalate PTFE vessels 3 L capacity each containing 2. Handbook of Phycological Methods. Analysis of effective light in different photobioreactors: La microalga Scenedesmus obliquus fue inmovilizada en esferas de Ca-alginato en dos densidades celulares del cultivo 6. This could be advantageous, because the cultures can work with a crecmiento range of intensity of light in tropical regions. Other factors scennedesmus as CO 2 and temperature should be taken into consideration.

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. Alginate beads as synthetic inoculant carriers for the slow release of bacteria that affect plant growth.

Immobilized microalgae for removing pollutants: Scenedesmus obliquus, photosynthesis, immobilized cells protein content. Factors affecting the growth characteristics of alginate-entrapped Chlorella.

Para facilitar la solubilidad de las esferas, se agitaron vigorosamente en un Shaker rotatorio a rpm Bashan, ; Bashan et al. Ten beads and stock suspensions of S.

Wastewater nutrients N and P removal by carrageenan and alginate immobilized Chlorella vulgaris. Elsevier Academic Press Amsterdam. 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.

Review of practical aspects.

Por otra parte, el scenedesmks de que S. Each species is usually characterized by a maximum growth rate under ideal conditions of growth Bartual et al. However, in the present study it was observed that the irradiance ranges matched the light levels used for the culture of this genus of microalgae Kaya et al.

Partitioning of transfer and carboxylation components of intracellular resistance to photosynthetic CO 2 fixation: Jeanfils and Collar reported for S. Physiology of alginate immobilized Chlorella. Nitrogen budget in Scenedesmus obliqqus cultures with artificial wastewater.

De-Bashan L, Bashan Dd. Alginate microbeads as inoculant carriers for plant growth-promoting bacteria. However, it can be observed that in contrast to free-cell cultures, the appropriate light intensity obtained within the light limitation zone P-I secnedesmus does not guarantee a high biomass production and protein content.

In the study of immobilized cells, the high activity associated to the high content of chlorophyll is related to the limitation of the light in the beads. Mendoza-Espinosa 2M.


Características fotosintéticas y crecimiento de Scenedesmus obliquus inmovilizada en alginato

Light and temperature effects on the growth rate of three freshwater algae isolated from a eutrophic lake. Use of immobilized algae for estimating bioavailable phosphorus released by zooplankton. Ammonia removal and biomass characteristic of alginate-immobilized Scenedesmus obliquus cultures treating real wastewater. Hyperconcentrated cultures of Scenedesmus obliquus: The beads in each reactor were kept in suspension and mixed by means xe small air diffusers through which compressed air filtered through an activated carbon filter was introduced.

A valid consideration is that if nutrients crecimifnto not limiting and physiological conditions are optimal, then the photosynthetic activity is controlled only by light intensity. 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. Analysis of the cellular density and proteins. Increased growth of the microalga Chlorella vulgaris when coimmobilized and cocultured in alginate beads with the plant-growth-promoting bacterium Azospirillum brasilense.

Growth The growth of immobilized S.


En un estudio sobre la ultraestructura de las esferas de alginato Lebsky et al. Culture Methods and Growth Measurement. Abstract The micfoalgae Scenedesmus obliquus was immobilized in Ca-alginate beads at two stocking cell densities 6.
