Nano ZnO is currently used in the rubber, electronics, electrical appliances, enamel, cosmeticsand medical industry. Whereas most studies have used the ecological toxicity of nanoparticles, the toxic effects of nanoparticles in diet is not extensively explored. Because the algaeare at the base of the food chain, any change in their density, biomass and population, wouldaffect the food chain in ...

This study was carried out to investigate the effect of different waters; tap water (control), sewage effluent (100 % & 50 %), sewage effluent with Scenedesmus quadricauda and sewage effluent with Nostoc sp. on plant growth, leaf chlorophyll and Assessment of hygienic (fungi) of wheat and alfalfa plants. The obtained results showed that plant height, herb weight (fresh and dry), total chlorophy...

In this study, effects of pH and salinity on growth and bloom of Dunaliella sp. algae were investigated. The algae were reared in different pH (6.0, 6.8, 7.0, 7.3, 7.6, 8.0, 8.6, 9.0, 9.7 and 11.0) and salinities (20.0, 31.6, 50.1, 79.4, 117.1, 125.9 and 200.0 ppt) at Inland Aquaculture Research Institute Phycolab during 2011. After 96 h, the algae reared in 50ppt salinity and below that had ne...

The industrial use of elicitors as alternative tools for disease control needs the identification of abundant sources of them. We report on an elicitor obtained from the green algae Ulva spp. A fraction containing most exclusively the sulfated polysaccharide known as ulvan-induced expression of a GUS gene placed under the control of a lipoxygenase gene promoter. Gene expression profiling was pe...

Sustainable diets are defined as those that present low impacts both on the environment and the biodiversity, contributing to food and nutrition security and to a healthy life for present and future generations. Algae (macroalgae and microalgae, including cyanobacteria) have recently taken an increased interest as valuable products, being used as ingredients or condiments in the modern diversif...

sulfated polysaccharides have shown promising effects on wound healing processes along with many other biological activities. the sulfated polysaccharides extracted from two algae species habitats in persian gulf were studied in vivo for their effects on collagen formation and epidermal regeneration. the polysaccharides were purified from aqueous extracts of p. tetrastromatica and p. boergeseni...

Abstract The current investigation intends to compare the compression strength analysis of glass fiber composites filled with brown algae filler. material involved in this work is a fibre composite and without 40 specimens were tested by using selected parameters universal testing machine. In work, control group was epoxy experimental algae-filled fiber-reinforced polymer. mean compressive obta...
