two iranian strains of brachionus rotifers were cultured under different food and salinity regimes. the rotiferswere fed with five algal types (freshwater and marine chlorella vulgaris, nannochloropsis occulata, isochrysisgalbana and scenedesmus obliquus) at three different salinities (5, 15 and 25 g/l) and their reproductive and growth parameters were assessed. the maximum number of ovigerous ...

Two species of microalgae growing as immobilized and free-cells were compared to test its ability to remove N and P in batch cultures of urban wastewater. The best microalgae-cell growth configuration was selected to be tested in bioreactor operated in semi-continuous mode. Scenedesmus obliquus showed a higher N and P uptake rate in urban wastewater than Chlorella vulgaris. When tested in semi-...

The aim of this study was to test three flat plate photobioreactor configurations for growth of Chlorella vulgaris under non-axenic conditions and to characterize and quantify associated bacterial communities. The photobioreactor cultivations were conducted using tap water-based media to introduce background bacterial population. Growth of algae was monitored over time with three independent me...

The green ciliate Paramecium bursaria contains several hundred symbiotic Chlorella species. We previously reported that symbiotic algal carbon fixation is enhanced by P. bursaria extracts and that the enhancing factor is a heat-stable, low-molecular-weight, water-soluble compound. To identify the factor, further experiments were carried out. The enhancing activity remained even when organic com...

in the present study, the effects of chlorella vulgaris on blood and immunological parameters of caspian salmon (salmo trutta caspius) before and after exposure to viral nervous necrosis (vnn) virus were examined. in this regard, four treatments in triplicate were chosen. groups included one control and 3treatments (t1, t2 and t3).  fish in control group, t1, t2 and t3 were fed diets supplement...
