“…There is a considerable literature on the treatment of municipal wastewater in high-rate ponds (Nurdogan and Oswald, 1995) and on the treatment of dairy and swine manures by monoalgal cultures such as Spirulina (Lincoln and Wilkie, 1995;Lincoln et al, 1996;Olguin et al, 1997).…”

“…The results showed 3158 mg/L biomass production of Spirulina. Lincoln et al (1996) used anaerobically digested cattle manure in 1:1 ratio for the cultivation of Spirulina. The yield of Spirulina biomass was found 70 mg/L/ d for laboratory experiments and 24 mg/L/d for outdoor cultivations.…”

Spirulina (Arthroapira) characterized by helical/spiral shape in open left hand helix is a multicellular, free floating cyanobacterium or blue green alga. Its trichomes are cylindrical arranged in unbranched form and the width ranges from 6 to 12 µm. The basic helical feature of its filaments is unique and can be found only in liquid culture medium. Spirulina has been so popular in the world due to its high nutritional contents. It has been used as protein and vitamin supplement to the health food industry, in aquaculture diets and fisheries. Cyanobacterium Spirulina is capable to grow in various kinds of culture media. Furthermore, decomposed organic and inorganic nutrients media have been proven to be good source of culture medium for Spirulina cultivation by many researchers. Among many strains, Spirulina platensis has been cultured in various waste organic matters to evaluate its growth and biochemical components under similar controlled culture conditions. The present investigation was carried out to formulate a low cost medium using cow dung ash for the biomass production of S. platensis. Different concentration gradients of cow dung ash medium i.e. 10-60% with standard medium were analyzed for Spirulina growth at pH 9.5 ± 2, temperature 28°C ± 2 and light intensity 3 Klux. Success of the experiment was found in 20% concentration level (1.212 g/l dry biomass) having 20% cow dung ash supplemented with 80% prescribed medium i.e. CFTRI medium. The maximum removal efficiency of 20% CDAM at the end of experiment was measured at 98.06%, 51%, 83.64% and 51.01% for TSS, TDS, COD and conductivity respectively. These results indicate the potentiality of cow dung ash to provide the nutrients to the culture medium that reduces its valuable cost and make it a cheaper and economic culture for S. platensis. The nutritional status of S. platensis cultured in 20% CDAM suggested that the biomass of Spirulina is nutritionally rich as per standard.

“…In some instances they have been found to be useful as low cost converters of odour causing and pollution creating dairy effluents into micro-algal biomass using sunlight (Lincoln et al, 1996). They were found to be very effective in removing NH 4 ions and other nitrogen rich compounds from such effluents.…”

“…Some of these organisms and symbiotic systems like Azolla are used as biofertilizers, particularly in rice production (Venkataraman, 1972 andAzolla Utilization, 1987). They are also applied in oxidation ponds and sewage and sludge treatment plants (Lincoln et al, 1996). Recently a few species have been investigated for biofuel production because their ability to convert solar energy has been found to be the most efficient among all living organisms.…”

Cyanobacteria are among the earliest of inhabitants of Planet Earth and their existence can be traced back to 3.8 billion years. Their oxygenic photosynthesis led to the gradual conversion of the Earth"s atmosphere from an anaerobic to an aerobic one. This change enabled the advent of aerobic organisms that eventually underwent rapid evolution and became the dominant, highly diverse members of the current global biodiversity. Cyanobacteria are ubiquitous in their distribution and are found in all the latitudes from Arctic and Anatarctic regions to the Tropical deserts perhaps reflecting their pioneering habitation of the primitive earth. They are also unique in their ability to simultaneously perform oxygenic photosynthesis and oxygen labile nitrogen fixation. Through these processes they make significant contributions to the Carbon and Nitrogen bio-geochemical cycles, particularly in the deep oceans. The ability of these organisms to fix N 2 either independently or in symbiosis with other organisms not only contributes to natural ecosystems but is applied in certain countries particularly for rice cultivation. Their ability to grow in highly polluted environments is also used in the treatment of sewage and industrial effluents. Cyanobacteria are the most efficient among all living organisms in the harvesting of solar energy and are currently looked at as highly attractive candidates for biofuel production. A few species are being used for the production of highly nutritive food supplements. On the negative side, some cyanobacteria form massive growths called "blooms" in water bodies and many of them produce toxins harmful to fish, digastric animals and are suspected to be responsible for certain human ailments. Having reviewed most of these aspects of cyanobacteria, it is concluded that knowledge on these little known organisms would be invaluable not only for students, scientists and environmentalists but also for industrialists and policy makers.
