Abstract

Microalgae are unicellular photosynthetic organisms that have been recently attracted potential interests and have applications in food, nutraceuticals, pharmaceuticals, animal feed, cosmetics, and biofertilizers industry. Microalgae are rich in a variety of high-value bioactive compounds which have potential benefits on human health and can be used for the prevention and curing of many disease conditions. But scale-up and safety issues remain a major challenge in the commercialization of microalgal products in a cost-effective manner. However, techniques have been developed to overcome these challenges and successfully selling the products derived from microalgae as food, cosmetics and pharmaceutical industries. Microalgae are rich in many nutrients and can be used for the production of functional food and nutraceuticals, safety and regulatory issues are major concerns and extensive research is still needed to make microalgae a commercial success in the future. Many practical difficulties are involved in making the microalgal food industry commercially viable. The present review focuses on the industrial applications of microalgae and the challenges faced during commercial production.
