ALGAL BIOMASS FROM Fucus vesiculosus (Phaeophyta): INVESTIGATION OF THE MINERAL AND ALGINATE COMPONENTS
Mineral composition of algal biomass from Fucus vesiculosus (the Baltic Sea, Estonia) is rich in light elements (Mg, K, Ca, Na) and halogens (Br, I). Arsenic content is also high (over 300 ppm); the content of other toxic elements (Hg, Sb, Se, etc.) is extremely low. Mineralization of the algal whole biomass does not depend on seasonal varieties. The content of α-L-guluronic acid residues, and ...
متن کاملBiosorption of Copper Ions by Marine Brown Alga Fucus vesiculosus
Copper is present in different types of industrial effluents, being responsible for environmental pollution. Biosorption of heavy metals can be an effective process for the removal and recovery of heavy metal ions from aqueous solutions. The biomass of marine algae has been reported to have high uptake capacities for a number of heavy metal ions. In this paper, the adsorption properties of a pr...
متن کاملSeasonal Variations in Surface Metabolite Composition of Fucus vesiculosus and Fucus serratus from the Baltic Sea
Perennial macroalgae within the genus Fucus are known to exude metabolites through their outer thallus surface. Some of these metabolites have pro- and/or antifouling properties. Seasonal fluctuations of natural fouling pressure and chemical fouling control strength against micro- and macrofoulers have previously been observed in Fucus, suggesting that control strength varies with threat. To da...
متن کاملFrequent Clonality in Fucoids (fucus Radicans and Fucus Vesiculosus; Fucales, Phaeophyceae) in the Baltic Sea(1).
Asexual reproduction by cloning may affect the genetic structure of populations, their potential to evolve, and, among foundation species, contributions to ecosystem functions. Macroalgae of the genus Fucus are known to produce attached plants only by sexual recruitment. Recently, however, clones of attached plants recruited by asexual reproduction were observed in a few populations of Fucus ra...
متن کاملFine-structural studies of the gametes and embryo of Fucus vesiculosus L. (Phaeophyta). II. The cytoplasm of the egg and young zygote.
Following fertilization, there are rapid changes in the appearance of the Fucus egg. Large electron-translucent vesicles (V1) accumulate fibrillar material, and following pronuclear fusion, they are largely electron-opaque. These vesicles (V1) are formed originally in unfertilized eggs by smooth endoplasmic reticulum (SER) after release of the eggs from the oogonium. Golgi complex hypertrophy f...
