Phytoplankton species composition as well as amount of Chlorophyll-a and their relation to physico-chemical parameters were studied. The samples were collected monthly from October 1996 until September 1997 in two stations, i.e. Lavan and Douberkeh coastal waters. In this study, 65 phytoplankton species related to 3 groups of diatoms, dinoflagellats and Blue-Green Algae (24 genus and 44 species...

Aquatic biomass, in general, and algae, in particular, are gaining attention for wastewater treatment and as a feedstock for renewable fuels. Research into algae biofuels is receiving significant attention because of the potential for providing high amounts of fuel with low land use. Several obstacles still remain especially in the area of algae selection, bioreactor choice, conversion to fuel ...

Algae biodiesel is an opportunity space that has gained renewed interest for venture investment. As with any new opportunity space, determining where the greatest value capturing potential resides has important implications for directing investment and research. This paper presents a value chain analysis of algae biodiesel and maps current industry players against similar segments in the biofue...

Marine algae are significant ingredients to formulate drugs for treating disease as they possess various bioactive potentials. This review expansively compares the antiinflammatory compounds from different marine algae. The anti-inflammatory effects of several different crude extracts and pure compounds of algae have been evaluated.Natural products from marine algae have potential resources in ...

Solar ultraviolet radiation (UVR) can reduce the photosynthesis and growth of benthic diatom communities in shallow freshwater. Nevertheless, greater amounts of algae accumulate in UVR-exposed habitats than in UVR-protected environments. Near-ultraviolet (UVA wavelengths of 320 to 400 nanometers) and mid-ultraviolet (UVB, wavelengths of 280 to 320 nanometers) radiation also inhibit algal consum...

A polarographic oxygen determination, with tissue in direct contact with a stationary platinum electrode, has been used to measure the photosynthetic response of marine algae. These were exposed to monochromatic light, of equal energy, at some 35 points through the visible spectrum (derived from a monochromator). Ulva and Monostroma (green algae) show action spectra which correspond very closel...

Using the large subunit of RuBisCo (rbcL) sequences from cyanobacteria, proteobacteria, and diverse groups of algae and green plants, we evaluated the plastid relationship between haptophytes and heterokont algae. The rbcL sequences were determined from three taxa of heterokont algae (Bumilleriopsis filiformis, Pelagomonas calceolata, and Pseudopedinella elastica) and added to 25 published sequ...

Shewanella algae infections are rare in humans. Previously reported cases of S. algae have mainly been associated with direct contact with seawater. We report a case of primary S. algae bacteremia occurring after the ingestion of raw seafood in a patient with liver cirrhosis that presented a fulminent course of necrotizing fasciitis.

Background and purpose: Osteoporosis is a silent disease which is causing death of significant population due to bone fractures. Use of natural supplements is considered with respect to side effects of chemical drugs. In this study, the effect of sargassum algae on osteoporosis disease was investigated. Method: The study was done on 80 mice heads of NMRI race. After osteoporosis induction, t...

In this paper, we report an in vitro co-culture system that combines mammalian cells and algae, Chlorococcum littorale, to create a three-dimensional (3-D) tissue. While the C2C12 mouse myoblasts and rat cardiac cells consumed oxygen actively, intense oxygen production was accounted for by the algae even in the co-culture system. Although cell metabolism within thicker cardiac cell-layered tiss...
