"Growing Spirulina on a large scale is beneficial both environmntally and nutritionally for humans," justify.
Spirulina is a cyanobacteria which can be used as Single cell protein (SCP). SCP are the alternate sources of edible proteins derived from micro-organism for animal and human nutrition. Microbes like Spirulina can be grown easily on the materials like waste water containing starch, straw, molasses, animal manure and even sewage. Such utilisation of substrates thus reduce environmental pollution. Also these microbes serve as a great source of nutrition as they are rich in proteins, minerals, fats, carbohyderates and vitamins. Thus growing such microbes on a large scale is beneficial both environmentally and nutritionally for humans.
