The green seaweed Ulva is a major fouling organism but also an edible aquaculture product in Asia. This study quantified for the first time the effect of key factors on the reproduction of a tropical species of filamentous Ulva (Ulva sp. 3). The controlled timing of release of swarmers (motile reproductive bodies) was achieved when experiments were initiated in the early afternoon by exposing t...

Ulva flexuosa, one kind of green tide algae, has outbroken in the Yellow Sea of China during the past ten years. In the present study, we sequenced the chloroplast genome of U. flexuosa followed by annotation and comparative analysis. It indicated that the chloroplast genomes had high conservation among Ulva spp., and high rearrangement outside them. Though U. flexuosa was closer to U. linza th...

Green algae are of great economic importance. Seaweed is consumed fresh or as seasoning in Japan. The commercial value is determined by quality, color, and flavor and is also strongly influenced by the production area. Our research, based on solid phase microextraction gas chromatography mass spectrometry (SPME-GC-MS), has revealed that volatile compounds differ intensely in the four varieties ...

Sulfated polysaccharides (SPs) extracted from five seaweed samples collected or cultivated in Mexico (Macrocystis pyrifera, Eisenia arborea, Pelvetia compressa, Ulva intestinalis, and Solieria filiformis) were tested in this study in order to evaluate their effect on measles virus in vitro. All polysaccharides showed antiviral activity (as measured by the reduction of syncytia formation) and lo...

There is an increasing demand for sustainably produced, protein-rich, and nutritious food. Seaweeds are promising protein sources the future if their content can be optimized, something which achieved by cultivation in elevated nutrient concentrations. Cultivation of seaweeds integration with fish farms have received much attention lately, but using nutrient-rich process waters from other food ...

Food resources are limited in arid countries such as the United Arab Emirates (UAE); salinity of groundwater, together with a lack natural fresh water sources and arable land, force country to import most its food. However, seaweed could play an important role providing locally available food resource, it does not require land grow. The traditional use several species has been documented Asia A...
