    Cyanobacteria (blue-green algae) Cyanobacteria, also known as Blue-green algae, (Cyanophyta), (Myxophyta) and (Cyanochloronta) are difficult to classify, and there are numerous schools of thought on their Taxonomy. Cyanobacteria are prokaryotic organisms however posess many of the same qualities as algae and therefore were previously categorized as such, hence the name blue-green algae. They form a class greatly dissimilar from that of other algae, and possess many of the same characteristics of

    Cyanobacteria Cyanobacteria are one of the largest and most important groups of bacteria on the earth. Often called ‘the blue-green algae’ Cyanobacteria is in fact, not an algae at all. Algae are eukaryotic, whereas cyanobacteria, is a bacteria, and is prokaryotic. The name algae is used to refer to any aquatic organisms capable of photosynthesis, so the term is considered general, though in this case, inaccurate. Being tiny and normally unicellular, cyanobacteria grow in large colonies, making them

    Introduction Cyanobacteria are photosynthetic ubiquitous microorganisms involved in the oxygenation of Earth’s atmosphere during the Great Oxidation Event that occurred 2.4 billion years ago (Rasmussen, Fletcher, Brocks, & Kilburn, 2008). Cyanobacteria have colonized a broad range of different habitats on Earth and are easily found in freshwater, brackish, marine and soil environments (Whitton, 2012), but also in extreme environments such as deserts, hot spring waters (Sompong, Hawkins, Besley, &

    what effect agricultural runoff has on surrounding environment, and to find what solutions can be made to reverse any damage. Introduction: There are many different species of algae. One of the most common algae, blue-green algae, is a type of cyanobacteria. One species of this is the Chlorella regularis, single celled algae that stays alive through the process of photosynthesis. The growth of algae depends on a variety of factors, such as the nutrients in that environment, temperature, light levels

    Water treatment process overview The first step in creating a cyanobacteria-directed biodesalination apparatus is selecting a species that possesses proper metabolic and morphologic characteristics. The organism must then be genetically modified to optimize ion regulation, and light regulation of the desalination process. Cyanobacteria use photosynthesis for removal of sodium from the intracellular matrix of the bacterium. Through regulation and genetically modifying the bacteria to express halorhodopsin

    Desert Ecosystems Communities of micro-organisms create crusts on soils throughout semi-arid and arid regions of the world. These microphytic (also called cryptogamic) crusts are formed when all or some of a diverse array of photosynthetic cyanobacteria (blue-green algae), fungi, bacteria, lichens and mosses, bind together with inorganic particles in the first few millimeters of a soil. Microphytic crusts are dominant feature in desert soils; they are estimated to represent approximately 70%

They can produce, replicate, continue homeostasis, familiarize, and grow. Abiotic Components: The abiotic mechanisms comprise the vitality twisted over the pedaling of nutrients, the stellar dynamism, and other dead mechanisms in the environment. The abiotic constituents of the system can be hotness, sunlit, airborne existing, etc. Limiting factors: To one side after

    of the Canadian Lakes including Lake Winnipeg. Since 1969, it has been observed that Cyanobacteria (blue-green algae) has been the reason for the 90% hike in the algal blooms.Cyanobacteria causes a smelly odour and releases toxins that are detrimental to humans and some other organisms. When the lake is enriched with phosphorus, cyanobacteria thrive due to nitrogen-fixing. Due to the unfair advantage cyanobacteria has over other non-nitrogen-fixing species and its cause in oxygen depletion, other

    • 2 Pages

    Diatoms are a unicellular phytoplankton that survives by floating in the ocean and are in the class Bacillariophyta. Diatoms are even the most common type of life in the ocean. This organism is similar to plants because of the photosynthetic qualities they posses. Diatoms use photosynthesis to absorb light, yet the pigment they possess is brown. Such aspects relate diatoms to brown algae. For this reason, scientists typically place them in the plant kingdom but others state today they are in the
