EVALUACIÓN DEL CRECIMIENTO DE LA MICROALGA Scenedesmus sp. E by on Prezi

However, in immobilized cells this can represent a disadvantage, as the high cell density would cause light limitation within beads followed by lower growth and nutrients removal capacity. Results and Discussion Activity of immobilized algae The photosynthetic rates reached for high and low sceendesmus density of immobilized S. Growth The growth of immobilized S.

Services on Demand Article. However, there are few studies about the photosynthetic characteristics of S. Cultures of immobilized S. Universidad Jorge Tadeo Lozano; Se destaca el estudio de Twist et al.

Mendoza-Espinosa 2M. This could be advantageous, because the cultures can work with a wide range of intensity of light in tropical regions.

Nitrite uptake by Chlamydomonas reinhardtii cells immobilized in calcium alginate. Both irradiances showed that only around 5.

Analysis of effective light in different photobioreactors: Microalgae growth-promoting bacteria as ”helpers” for microalgae: Freshwater algae of North America. A similar trend was reported by Bartual et al. Therefore, it was concluded that the light intensities selected in the present study not had significant effects in the growth and protein content in beads with low cells stocking.

Each reactor was operated with a beads concentration of approximately 2. This difference is attributed to the fact that the photosynthetic rate was estimated to a light intensity 60 W m -2 and not for a maximum obtained to different intensities photosynthetic curve as reported in the present study. Para facilitar la solubilidad de las esferas, se agitaron vigorosamente en un Shaker rotatorio a rpm Bashan, ; Bashan et al. It is possible to reach high contents of chlorophyll and high photosynthetic rates for immobilized cells in alginate for species such as Chlorella sp.

Universidad scendesmus Antioquia; Effects of different methods of processing on the protein efficiency ratio of the green alga Scenedesmus acutus. Culture Methods and Growth Measurement.

Bajo estos modelos ajustados S. The changes in P max ratio in relation to the initial acenedesmus density within beads allowed to reach the best conditions for the immobilized systems.

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. Reactors consisted of cylindrical transparent polyethylene terephthalate PTFE vessels 3 L capacity each containing 2.

Cambridge University Press; These results are useful for subsequent applications of the encapsulated algae, such as biomonitoring and bioremediation. Other factors such as CO 2 and temperature should be taken into consideration.

Immobilization of Botryococcus braunii in alginate: 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.

Scenedesmus ovalternus and Chlorella vulgaris species were used. 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. Effect of intermittent CO 2 enrichment during nutrient starvation on tertiary treatment of wastewater by alginate-immobilized Scenedesmus bicellularis.

Por otra parte, el hecho de que S. The micfoalgae Scenedesmus obliquus was immobilized in Ca-alginate beads at two stocking cell densities 6. Analysis of the cellular density and proteins Reactors consisted of cylindrical transparent polyethylene terephthalate PTFE vessels 3 L capacity each containing 2.

Statistical analyses The photosynthetic rate data in the experiments with two cellular densities in alginate beads were analyzed by analysis of variance ANOVA.

The high activity associated to the high content of chlorophyll is related to the limitation of the light in the beads.
