Abstract
The term Algae contains both unicellular and multicellular organisms. It also includes organisms size ranging from micro- to macro-level. According to Botanical survey of India, 7411 species of algae were present in India, which includes both fresh water and marine algae. Iyengar referred as the father of India Algology. Nitrogen-fixing cyanobacteria (e.g., Anabaena, Nostoc) are used as natural fertilizers in India and other parts of Asia, where they reduce the need for expensive synthetic fertilizers in rice farming. Microalgae contain up to 50-70% protein, 30% lipids, over 40% glycerol, upto 8-14% carotene and a high concentration of vitamins B1, B2, B3, B6, B12, E, K, D, etc., compared to terrestrial plants and animals.
