Organic compounds including seaweed extract were applied in organic production system and sustainable agriculture. One of these compounds is humic acid that was used widely in research and commercial programs. Humic acid is an organic acid obtained from humus and other natural resources with hormonal effects and improving nutrient absorption, increasing root and shoot biomass. In order to inves...

BACKGROUND The biosynthesis of metal nanoparticles by marine resources is thought to be clean, nontoxic, and environmentally acceptable "green procedures". Marine ecosystems are very important for the overall health of both marine and terrestrial environments. The use of natural sources like Marine biological resources essential for nanotechnology. Seaweeds constitute one of the commercially im...

The ability of crude extracts of the brown seaweed Spatoglossum schröederi to counteract some of the biological activities of Lachesis muta snake venom was evaluated. In vitro assays showed that only the extract of S. schröederi prepared in ethyl acetate was able to inhibit the clotting of fibrinogen induced by L. muta venom. On the other hand, all extracts were able to inhibit partially the he...

China is facing intense coastal eutrophication. Large-scale seaweed aquaculture in China is popular, now accounting for over 2/3's of global production. Here, we estimate the nutrient removal capability of large-scale Chinese seaweed farms to determine its significance in mitigating eutrophication. We combined estimates of yield and nutrient concentration of Chinese seaweed aquaculture to quant...

Rocha is a Portuguese pear cultivar with high economic importance in the Western Region. Degradative processes following its manipulation can quickly lead to product rejection, especially when sold as fresh-cut product. The efficacy of marine-based edible coating inhibit superficial browning development slices was investigated over storage period 15 days. aqueous extract Codium tomentosum, an g...

The effect of Sargassum pallidum (brown seaweed) aqueous extract on the immunity function and antioxidant activities in was studied gastric cancer rats. Treatment with Sargassum pallidum aqueous extract at oral doses 400, 600 or 800 mg/kg body weight was found to provide a dose-dependent protection against N-methyl-N′-nitro-Nnitrosoguanidine (MNNG)-induced immunity damage and oxidative injury b...

Shrimp aquaculture has expanded rapidly in many countries and this rapid development resulted diseases outbreaks and further considerable utilization  of antibiotics. Use of natural products as antimicrobial has been reported as a resolution problem. The crude extract of a red seaweed (Laurencia snyderiae) collected from the Persian Gulf was evaluated for shrimp growth performance and to d...
