Kinetics Of

The kinetics of incorporation of 32P from orthophosphate-32P or DL-α-glycerophosphate-32P into the phosphatides of Chlorella vulgaris during photosynthesis was studied. Rapid labelling of phosphatidyl glycerol was observed with both precursors, followed by lower rates of incorporation into lecithin, phosphatidyl ethanolamine, and phosphatidyl inositol. The results are discussed in the light of biosynthetic pathways known for animal and bacterial cells.

En este trabajo se describe la técnica de inmovilización de microalgas en esferas de alginato de calcio. Se emplearon las especies Scenedesmus ovalternus y Chlorella vulgaris, se determinó la estabilidad de las esferas, la cinética de crecimiento y la concentración de las microalgas en el interior de las esferas. Chlorella vulgaris alcanzó mayores densidades poblacionales y tasas de crecimiento más altas cuando se inmovilizó en concentraciones del 10 % v/v con el alginato (1,31*106 cél/ml). Para Scenedesmus ovalternus se observó una mayor densidad poblacional y una mayor tasa de crecimiento cuando se inmovilizó en concentraciones del 20 % v/v (7,06*105 cél/ml). Estos resultados son útiles para aplicaciones prácticas de las algas encapsuladas, tales como el biomonitoreo o la biorremediación.Immobilization of Microalgae Scenedesmus ovalternus (Scenedesmaceae) and Chlorella vulgaris (Chlorellaceae) in Calcium Alginate BeadsThis paper describes the immobilization technique of microalgae in calcium alginate beads. Scenedesmus ovalternus and Chlorella vulgaris species were used. The stability of beads, the kinetics of growth and the concentrations of microalgae inside the beads were determined. The higher density and the upper growth rate of Chlorella vulgaris occurred when it was immobilized in alginate at a concentration of 10 %v/v (1,31*106 cél/ml). Scenedesmus ovalternus achieved a higher population density and an elevated growth rate when it was immobilized at a concentration of 20 % v/v (7,06*105 cél/ml). These results are useful for subsequent applications of the encapsulated algae, such as biomonitoring and bioremediation.

Environmental context Interaction of metals with dissolved organic matter is one of the key processes defining metal bioavailability in water. The technique of diffusive gradients in thin films was used to investigate the kinetics of the interaction between metals and dissolved organic matter released by algae. For most metals the rate at which they were released from the organic matter was fast, but release of iron was kinetically limited. AbstractThe interaction of metals with organic matter is one of the key processes determining metal speciation and bioavailability in water. Fulvic acid tends to dominate dissolved organic carbon (DOC) in freshwaters, but organic carbon produced in situ, e.g. exudates released by algae and bacteria, is also significant. The technique of diffusive gradients in thin films (DGT) was used to investigate the lability of metal–exudate complexes using a kinetic signature approach. Exudates were harvested from three cultured freshwater alga (Chlorella vulgaris, Cryptomonas pyrenoidifera, Anabaena flos-aquae) and the filtered media supplemented with trace metals. DGT-labile metal concentrations and kinetic signatures were determined (24-h deployment). The relationship between Fe and DOC was a defining feature of the kinetic signatures. Iron was the most kinetically limited metal followed by Al and Cu, whereas Co, Ni and Pb were effectively completely labile. Exudates from Chlorella vulgaris produced the most DOC and the most marked kinetic limitation.
