The ecology of phytoplankton. Bajo estos modelos ajustados S. Stock suspension of S.

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

Other factors such as CO 2 and temperature should be taken into consideration. Effect of irradiance on growth, photosynthesis, pigment content and nutrient consumption in dense cultures of Rhodomonas salina Wislouch Cryptophyceae.

Alginate from the macroalgae Sargassum sinicola as a novel source for microbial immobilization material in wastewater treatment and scenedesnus growth promotion. The relationship between photosynthesis and light for natural assemblages of coastal marine phytoplankton. scenrdesmus

This paper describes the immobilization technique of scenedesmjs in calcium alginate beads. Dry weigh, packed cell volume and optical density. Taking into consideration the amount of ammonium at the end of the 42 h of cultivation 6.

The photosynthetic parameters obtained for immobilized S. Biological tertiary treatment of urban wastewaters with chitosan-immobilized Phormidium.

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

The growth of immobilized S. The changes in P max ratio in relation to the initial cellular density within beads allowed to reach the best conditions for the immobilized systems.


Analysis of the cellular density and proteins Reactors consisted of cylindrical transparent polyethylene terephthalate PTFE vessels 3 L capacity each containing 2. Physiology of alginate immobilized Scennedesmus. Efficiency of immobilized hyperconcentrated algae for ammonium and orthophosphorus removal from wastewater. However, in contrast to free-cell cultures, the appropriate light intensity obtained within the light limitation zone P-I curves did not cause a high biomass production and protein content.

This may be caused by the previous adaptation of S. 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. Abstract The micfoalgae Scenedesmus obliquus was immobilized in Ca-alginate beads at two stocking cell densities 6.

Role of glutamate scenedeemus and glutamine synthetase in Chlorella vulgaris during assimilation of ammonium when jointly immobilized with the microalgae-growth-promoting bacterium Azospirillum brasilense. The pH did not seem to interfere with algal growth. Growth The growth of immobilized S. Universidad Jorge Tadeo Lozano; Review of practical aspects.


This cellular concentration was higher than that obtained at UE m -2 s -1 from 3. Materials and Methods Routine of culture Stock suspension of S. 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.

En un estudio sobre la ultraestructura drecimiento las esferas de alginato Lebsky et al. Reactors consisted of cylindrical transparent polyethylene terephthalate PTFE vessels 3 L capacity each containing 2. 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.

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

Protein measurement with the Folin phenol reagent. Effects of different methods of processing on the protein efficiency ratio of the green alga Scenedesmus acutus. En el caso de C. Analysis of effective light in different photobioreactors: Scenedesmus obliquus, photosynthesis, immobilized cells protein content.

However, there are few studies about the photosynthetic characteristics of S. In situ measurement of microalgal growth potential in aquatic ecosystems by immobilized algae.

Wastewater nutrients N and P removal by carrageenan and alginate immobilized Chlorella vulgaris. Photosynthetic rates P of immobilized cell cultures of S.
