The production and use areas of aquatic plants are investigated in the article. In recent times, development fishing all-round (as food, purchase environmentally oil, as fertilizer) is one main issues our day. Macroalgae basis cultivated sea products. Mainly, brown algae — laminaria, fucus, red Kappaphycus alvarezii Eucheuma widely used for both food alginate production. Spirulina algae, a repr...

Inositol and choline were present in varying amounts among the species of Rhodophyta, Phaeophyta, Chlorophyta, and Euglenophyta examined. However, in the two members of the order Fucales (division Phaeophyta) examined, no detectable amounts of choline were found. In contrast, the species of Cyanophyta examined contained no detectable amounts of either choline or inositol. All species of the fun...

Cyanobacteria (blue-green algae) are abundant in fresh, brackish and marine waters worldwide. When toxins produced by cyanobacteria are present in the aquatic environment, seafood harvested from these waters may present a health hazard to consumers. Toxicity hazards from seafood have been internationally recognised when the source is from marine algae (dinoflagellates and diatoms), but to date ...

Rates of grazing on phytoplankton by macrozooplankton (cladocerans and copepods > 220 μm in length) and microzooplankton (animals < 220 μm, mostly rotifers and nauplii) were determined for Lake Champlain on three occasions using a modified version of the Lehman-Sandgren method. Gradients in grazer density were created in fertilized cubitainers incubated in situ, and clearance rates on specific ...

Algae are highly diverse in their habitat and properties: unicellular such as Chlorella sp. [1]. And the diatoms, to multicellular forms, such as the giant kelp, a large brown alga. Algae are eukaryotes though Cyanobacteria or Blue-green algae (like Lyngbya) [2], are Prokaryotic; but some researchers don’t consider Cyanobacteria as algae [3,4]. Algal Collection of the US National Herbarium (Nat...

The isolation and partial purification of mevalonic acid kinase from Euglena gracilis is described. The product of the reaction MVA-5-P has been characterized by paper chromatography. The apparent Km values for l-mevalonic acid, ATP, and Mg(2+) are 3 x 10(-5)m, 6 x 10(-3)m, and 9 x 10(-3)m, respectively. A concentration of 1 x 10(-3)mp-hydroxymercuribenzoate completely inactivates the enzyme. A...

Functional classification and composition of phytoplankton of Liman Lake were studied between January 2002 and December 2003. A total of 109 taxa belonging to Bacillariophyta, Chlorophyta, Cyanophyta, Dinophyta, Xantophyta, Chrysophyta and Cryptophyta were identified. The succession during 2002 began with R-Strategists (with a high surface to volume ratio, including blue-green algae with filame...
