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...

Daphnia p&x (Crustacea, Cladocera) was fed the blue-green algae (Cyanophyceae) Anacystis nidulans, Synechococcus elongata, S. cedrorum, Merismopedia sp., Anabaena flosaquae, Synechocystis sp., and Gloeocapsa alpicola. The green algae ( Chlorophyceae) Ankistrodesmus falcatus and Chlorella uulgaris were used for comparison. Direct observations were made of D. pulex feeding in depression slides fi...

Choline acetyltransferase was demonstrated in nettles (Urtica dioica), peas (Pisum sativum), spinach (Spinacia oleracea), sunflower (Helianthus annuus) and blue--green algae by using a Sepharose--CoASH affinity column. The column effected a 1500-fold purification of the enzyme from nettle homogenates and was required for demonstrating activity in the other higher plants. Demonstration of the en...

In this study the fresh water grown Blue-Green Algae (Anabaena ambigua) is studied for its maximum growth. This Blue-Green Algae (Anabaena ambigua) growth is studied in detail in three different media viz.,Fog’s media,BG-11, BBM , there was a significant change observed in growth of the species Anabaena ambigua at different light intensities and different media, during 15-days growth. Growth wa...

The rates of true and apparent photosynthesis of two unicellular green algae, one diatom and four blue-green algae were measured in buffer at pH 8.0 at subsaturating concentrations of dissolved inorganic carbon (13-27 micromolar). Initial rates of depletion from the medium of inorganic carbon and (14)C activity caused by the algae in a closed system were measured by gas chromatography and by li...

In the evolving health management paradigm,1-4 the general regulation of the immune system as well as the enhancement of specific immune functions have become a growing point of interest, and rightly so. Many health problems result from the inability of the immune system to stop a disease process in its initial stage. This paper will review the scientific evidence for the immunomodulatory effec...
