Toxic And Anti-Cancerogenic Effect Of Brown Seaweed Cystoseira Tamariscifolia
Cystoseira tamariscifolia is a brown alga which represents an important natural biomass on the Moroccan Atlantic coast. Study of the acute toxicity of this species was carried out on Swiss albinos mice. The LD50 was determined through the Spearman-Karber method by injecting the aqueous algal extract to 36 mice organized in lots of 6 animals each for 6 concentrations and the experiments were con...
متن کاملRemoval of Trivalent and Hexavalent Chromium by Seaweed Biosorbent
Protonated or Ca-form Sargassum seaweed biomass bound up to 40 mg/g of Cr(III) by ion exchange at pH 4. An ion-exchange model assuming that the only species taken up by the biomass was Cr(OH)2+ successfully fitted the experimental biosorption data for Cr(III). The maximum uptake of Cr(VI) by protonated Sargassum biomass at pH 2 was explained by simultaneous anion exchange and Cr(VI) to Cr(III) ...
متن کاملBiosorption of trivalent chromium on the brown seaweed biomass.
Biosorption has attracted attention as a cost-effective means for the treatment of metal-bearing wastewater. However, the mechanism of metal binding is not clearly understood, and consequently, modeling of the biosorption performance is still raising debates. In this study, the biosorption of trivalent chromium was investigated with protonated brown alga Ecklonia biomass as a model system. Titr...
متن کاملبررسی تاثیر غلظت و نرخ جریان ورودی به ستون بستر ثابت بر روی عملکرد جذب زیستی نیکل توسط جلبک قهوه‌ای پروتونه شده Cystoseira indica و مدل‌سازی نتایج تجربی
Background and Objectives: Biosorption is a new and inexpensive technique in heavy metals removal and recovery from aqueous solutions. In order to evaluate the potential of this method for the removal of nickel ions, biosorption of nickel ions from aqueous solution was studied using Cystoseira indica biomass in a packed bed column. Materials and Methods: The uptake capacity of nickel ions was...
متن کاملStructural features and antiviral activity of sulphated fucans from the brown seaweed Cystoseira indica.
Natural compounds offer interesting pharmacological perspectives for antiviral drug development. In this study, we have analysed sulphated-fucan-containing fractions isolated from the brown seaweed Cystoseira indica. The crude water extract (CiWE) and the main fraction (CiF3) obtained by anion exchange chromatography had potent antiviral activity against herpes simplex virus types 1 (HSV-1) and...
