The antioxidant activities of Ulva faciata, Nizimuddinia zanardinii and Gracilaria corticata were investigated in Chabahar, Iran. Methanol extract and n-hexane, dichloromethane and ethylacetate fractions used for antioxidative properties test by the total antioxidative activity, 2,2-diphenyl-1-picryl-hydrazylhydrate (DPPH)  free radical scavenging activity, reduction power, metal chelating acti...

The green algae Ulva faciata was subjected to different physical pretreatments comprising thermal and mechanical techniques at experimental conditions state the most appropriate method of cell disruption for increasing quantity extracted lipid hence improve quality produced biodiesel with low cost. Thermal pretreatment autoclaving either wet or dry algal biomass, while include microwave ultraso...

The increasing usage of chemical control agents, as well fungicides to manage plant diseases, causes human and environmental health problems. Macroalgae represent a reservoir for tremendous variety secondary metabolites that display wide range biological activities. However, their anti-phytopathogenic properties are still being studied. current study was conducted investigate whether or not the...

The possibility of using freshwater Ulva (Chlorophyta) as a bioaccumulator of metals (Co, Cr, Cu, Mn and Zn) in lake and river water was examined weekly in the summer of 2010 in three types of samples: the water, the sediment and the thalli of Ulva. Samples of freshwater Ulva were collected from two aqueous ecosystems lie 250 km away from the basin of the Baltic Sea and 53 km from each other. A...

Green macroalgae, mostly represented by the Ulvophyceae, the main multicellular branch of the Chlorophyceae, constitute important primary producers of marine and brackish coastal ecosystems. Ulva or sea lettuce species are some of the most abundant representatives, being ubiquitous in coastal benthic communities around the world. Nonetheless the genus also remains largely understudied. This rev...

The green alga, sea-lettuce (Ulva sp), could be considered as a new source of dietary fibre. Ulva, however, contains high levels of sulphate, part of which is chemically bound in soluble polymers (ulvan). The purpose of this study was to assess the fermentation characteristics and sulphate metabolism of Ulva and ulvan by human faecal bacteria fermentation system using a semi-continuous fermente...

Ulva is a common component of marine intertidal flora in Australia with many species frequently observed along the Queensland coastline. Three species of Ulva, U. lactuca, U. intestinalis and U. prolifera were found to naturally occur at the Bribie Island Research Centre (BIRC) in Southeast Queensland. Studies were undertaken to establish the most optimal conditions for growing Ulva in the BIRC...
