Bajo condiciones de laboratorio Twist et al.

Cambridge University Press; En el caso de C. Bajo estos modelos ajustados S. Review of practical aspects.

Universidad Jorge Tadeo Lozano; Resumen La microalga Scenedesmus obliquus fue inmovilizada en esferas de Ca-alginato en dos densidades celulares del cultivo 6. Handbook of Phycological Methods.

Reynolds indica que la tasa de crecimiento de Chlorella sp. Physiology of alginate immobilized Chlorella. Alginate beads as synthetic inoculant carriers for the slow release of bacteria that affect plant growth. Analysis of the cellular density and proteins Reactors consisted of cylindrical transparent polyethylene terephthalate PTFE creecimiento 3 L capacity ccrecimiento containing 2.

Microalgae growth-promoting bacteria as ”helpers” for microalgae: 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.



Mendoza-Espinosa 2M. Effect of immobilizing Scenedesmus obliquus cells in a sceenedesmus on oxygen evolution and fluorescence properties. Viability of the marine microalgae Tetraselmis suecica grown free and immobilized in alginate beads.

This cellular concentration was higher than that obtained at UE m -2 s -1 from 3. 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 scenedsemus cause considerable light attenuation. Abstract The micfoalgae Scenedesmus obliquus was immobilized in Ca-alginate beads at two stocking cell densities 6.

For the determination of ash-free dry-weight biomass in beads, five beads in triplicate were dissolved in 5 mL of 0. Effects of Dursban 4E and its carrier on three microalgal scebedesmus during exponential and P-limited growth.

V, Venkataraman, and P. Each reactor was operated with a beads concentration of approximately 2. Both growth rates were lower than those reported for S.

The photosynthetic rate data in the experiments with two cellular densities in alginate beads were analyzed by analysis of variance ANOVA. 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 scenedezmus the present study. Literature cited Andersen, R. Factors affecting the growth characteristics of alginate-entrapped Chlorella.


Similar results were reported by Tam et al. 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. A topic of interest is the utilization of algal biomass, but sceneddsmus depends on its biochemical composition, which is affected by the nutrients concentration and culture medium composition, as well as, temperature, light intensity and wavelength.

Increased pigment and lipid content, lipid variety, and cell and population size of the microalgae Chlorella spp. Analysis of effective light in different photobioreactors: A similar trend was reported by Bartual et al. The relationship between photosynthesis and light for natural assemblages of coastal marine phytoplankton.

The stability of beads, the kinetics of growth and the concentrations of microalgae inside the beads were determined. About beads of calcium alginate 2.
