Algae are a diverse group of unicellular autotropic microorganisms. It is a free-floating and filament-shaped organism, in which the blade is the main site for photosynthesis. Hence, called a photosynthetic organism. Different types of algae are found in different types of climatic conditions. Algae are found in almost all adverse climates. Due to its vast chemical composition and content of bioactive substances attention of different industries like food, cosmetic pharmaceuticals, nutraceuticals, etc. are caught by it. Algae food products contain a high amount of nutrients, and cosmetic products protect from UV radiation and prevention of rough texture wrinkles of the skin, as they carry out both photosynthesis as well as nitrogen fixation, add organic matter (20 -30kg/ha/year)and maintain texture porosity, the structure of soil and can play an important role for reducing the problem of petrol, diesel. This review has been prepared to shed light on the wide uses of algae as food, fuel, cosmetic product biofertilizer and also to provide knowledge about different types of algae found in different geographical zones of Nepal.
