Microalgae, a renewable source for lipid extraction, has mostly focused on biofuel production. There has been an inadequate study on food oils from microalgae. Microalgae grow in seawater, freshwater and wastewater. Comparable to terrestrial plants, microalgae use less land and water source and produce biomass ten times more than terrestrial plants. However, due to significant energy consumption, the economic viability of industrial-scale manufacturing is yet to be reached. The integrated system for microalgae oil production was developed to reduce energy consumption, be eco-friendly and produce value-added products.
