COURSE TITLE: PLANT PHYSIOLOGY Too much algal growth can have dire consequences for the water’s inhabitants - killing large numbers of fish, either by the toxic effects of the algae itself or de-oxygenation of the water. Blue-green algae have a high protein, iron, and other mineral content which is absorbed when taken orally. Also referred to as blue-green algae and blue-green bacteria, cyanobacteria is a bacteria phylum that obtain their energy through a process known as photosynthesis. The blue-green algae are most frequently involved in the con­tamination of water supplies, but the greens, the flagellated golden-brown, and the diatoms are also troublesome at times. Also called cyanobacteria, these organisms live in moist or aquatic environments just like other algae. Cyanobacteria (blue-green algae) In lakes and reservoirs, symptoms of eutrophic situations are the late summer cyanobacteria surface blooms that occur when the water is thermally stratified, sunlight intensity is high, there is a period of mild weather (low turbulence and calm winds) and the N:P ratio is low.

In the fishing industry; Fish farms have incurred losses of up to US $24 million after large-scale fish deaths as a consequence of an outbreak of toxic algae growth. Cyanobacteria were formerly classified as blue-green algae (les algues bleues in French, las algas azules in Spanish) because of their algal-like appearance, their possession of chlorophyll rather than bacteriochloro-phyll, and their photosynthetic production of oxygen by a two-photosystem process as in algae and higher plants. Monitoring blue green algae is an important priority for many individuals around the world. (See arrow on Photo 2.) Blue green algae has a dark green color, it is very slimy, it grows and spreads over any surfaces and has a specific bad smell.

The most common cyanobacteria toxins include the microcystins, cylindrospermopsins, anatoxins and saxitoxins. 'Bloom' is the term used to describe an accumulation of algal cells to a point where they discolour the water, form scums, produce unpleasant tastes and odours, affect fish populations and reduce the water quality. The advantage from using … Just to add to the confusion, blue-green algae also goes by other less common names. Blue Green Algae The use of algae in integrated aquaculture has also been recently reviewed by Turan (2009). Visitors tend to avoid areas where algae blooms have occurred as precaution, worsening the economic impact even more. Cyanobacteria, formerly called blue-green algae, are not really algae but are a phylum of photosynthetic bacteria that live in moist soils and water.The species' structures can be unicellular to filamentous and some species are colonial. Some of its examples are: (a) Anabaena is an important member. The most widespread of the cyanotoxins are the peptide toxins in the class called microcystins. They include about 2000 species in 150 genera, with a wide range of shapes and sizes. • Contain pigments • chlorophylls a, and many often have another chlorophyll, like b, c, or d and accessory red, blue and brown photosynthetic pigments 6. Aulosira, Anabaena, Cylindrospermum, Nostoc, Plectonema, Tolypothrix) in the paddy fields was realized much earlier (Singh, 1961). Blue-green algae can be classified as thermophilic (high tem-perature), mesophilic (room temperature), or psychrophilic (low temperature), according to the temperature ofthe culture media in whichthese organismsgrow. This is in large part due to Blue Green Algae’s content of carotenoids, fibers, plant sterols and other nutrients that may help in preventing inflammation. NOTE: No test is 100% perfect, and that includes the jar test for blue-greens. COURSE CODE: BOT-306 1. For example, it can be toxic if consumed. Cyanobacteria are also referred to as blue-green algae despite the fact of being distinct from algae.
