general toxicity, antiproliferative, antibacterial and antioxidant activities of caulerpa peltata j.v.lamouroux (caulerpaceae) collected from oman sea were investigated. dried, ground alga was soxhlet-extracted with hexane, dichloromethane and methanol successively. the methanol extract was subjected to vacuum liquid chromatography (vlc) fractionation on silica gel using a step gradient of diff...
BLACK Luffa sponge, derived from dried fruits of Luffa aegyptiaca Mill. (Sponge gourd, Hindi – Ghiya tori), could be a suitable matrix for tissue culture in aseptic liquid culture media. To test this, the response of aroid Philodendron ‘Xanadu’ Hort., an exquisite indoor-ornamental with its beautiful leaves and tangled aerial roots, was studied in vitro by Gangopadhyay and others. A study on in...
The green alga Caulerpa cylindracea is a non-autochthonous and invasive species that is severely affecting the native communities in the Mediterranean Sea. Recent researches show that the native edible fish Diplodus sargus actively feeds on this alga and cellular and physiological alterations have been related to the novel alimentary habits. The complex effects of such a trophic exposure to the...
The antinociceptive and anti-inflammatory activity of caulerpin was investigated. This bisindole alkaloid was isolated from the lipoid extract of Caulerpa racemosa and its structure was identified by spectroscopic methods, including IR and NMR techniques. The pharmacological assays used were the writhing and the hot plate tests, the formalin-induced pain, the capsaicin-induced ear edema and the...
Recent morphological and genetic studies on the Caulerpa racemosa (Forsskål) J. Agardh complex have demonstrated that three taxa occur in the Mediterranean Sea. One of them, the ‘invasive variety’, provisionally regarded as close to C. racemosa var. occidentalis J. Agardh, is currently spreading spectacularly throughout the Mediterranean. On the basis of new morphological and molecular studies ...
in this study caulerpa racemosa has been characterized and used for the removal of cd(ii) and pb (ii) from aqueous solutions. the effect of ph, adsorbent dosage, contact time and temperature on adsorption process was studied in batch experiments. langmuir and freundlich models were applied to describe the biosorption isotherm of the metal ions by c. racemosa biomass. the adsorption data can be ...
Stimulation of nitrogen fixation in refractory organic sediments by Caulerpa taxifolia (Chlorophyta)
Estimates of N2 fixation by substrata associated with the rhizophytic alga Caulerpa taxifolia were obtained using the acetylene reduction method. On average, growth of C. taxifolia enhanced rates of acetylene reduction in underlying dead sea grass sediments by a factor of 28, although the degree of enhancement was variable. The average rate of ethylene production was 3.96 nmol cm23 h21 (range 5...
