the antibacterial and antioxidant activities of methanol and acetone extracts of three marine algae, including hypnea hamulosa, gracilaria corticata and enteromorpha intestinalis wereinvestigated.antioxidant activities were determined by means of total antioxidant capacity, total phenolic compounds, dpph radical scavenging activity and ferric reducing antioxidant power. antibacterial activity w...
Some of the representatives from edible seaweeds (Gracilaria verrucosa, Gracilaria corticata, Turbinaria ornate, Sargassum polycystum) Kilinochchi and Kalpitiya in Sri Lanka were investigated for proximate composition (moisture, protein, lipid ash content). The was significantly (p < 0.001) different across seaweed species. In this regard, moisture content (mean ± SD) varied 76.33 0.0% T. or...
Monthly sampling of red algae was carried out from April 2005 to March 2006 in Chabahar coasts (southestern of Iran) along Sistan & Baluchistan province coastal waters. We considered monthly periods of maximum tide according to tide tables. Then seaweed growth area in intertidal zones was determind through GPS, GIS and satellite imagery. Monthly sampling was conducted on a number of transects w...
In the present study, two regulatory phytohormones, abscisic acid and auxin, were extracted from two different macroalgae, Sargassum muticum and Gracilaria corticata, for the first time. Sampling was performed each month with three replicates, from Bushehr Province shores located in the north region of Persian Gulf for six alternative months. The alteration of seaweeds biomass and the probable ...
Phytohormones are present in seaweeds but little is known about occurrence and content of them in seaweeds of Persian Gulf. The aim of this study was extraction of abscisic acid and gibberellin in Sargassum muticum and Gracilaria corticata. The seaweeds were collected bimonthly over one year at Bushehr coasts, Persian Gulf, during a range of environmental conditions. We explored new HPLC method...
herbal medicinal products have attracted significant research interest in recent years. considering the efficiency of algae products in controlling pathogenic bacteria and also easy access to large resources of algae, this study was conducted to evaluate the effects of methanolic, chloroformic and aqueous extracts of gracilaria salicornia against aeromonas hydrophila , a heterotrophic, gram-neg...
The nucleotide sequences of 5S rRNA from two red algae, Gracilaria compressa and Porphyra tenera have been determined. The two 5S rRNAs are fairly dissimilar to each other in their sequences (65% identity), although they are both composed of 121 nucleotides. Their secondary structures are generally of the eukaryotic with a prokaryotic characteristic. Judged from the 5S rRNA sequence data, the r...
