many studies on cold environments have been developed over the past two decades. highmountain freshwater presents high variability of nutrients and chemico-physical parameters, showing variations of ph, oxygen concentration, metals and temperature throughout the year. national park of sierra nevada (granada, spain) (37°032 n 03°182 w), has almost 40 lakes that are reported to be both endemic an...

in the present study the freshwater algae of siahdarvishan river were sampled on a montly basis from december 2007 through november 2008. three sampling stations (gaght roudkhan , shahkezr dame and talab laleh ) were chosen in the river. some physical and chemical parameters (water temperature , total hardness , nitrate , nitrite, phosphate and ph) of water samples were measured. a total of 84 ...

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...

Objective(s): Diabetes is a metabolic syndrome which is associated with the worldwide major public health problems. There are many natural compounds from the sea-market, as a valuable aquatic source, along with the variety of health and therapeutic benefits. In the present research, with respect to the traditional and ethnic uses of Sargassum oligocystum algae for healing of some diseases which...

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...
