Microalgae are unicellular and microscopic algae which are capable of performing photosynthesis, the conversion of CO2 using light energy.

Microalgae are a very diverse group of predominantly aquatic photosynthetic organisms including cyanobacteria, green algae, and diatoms.

Present in a wide range of aquatic environments from freshwater to saturated saline.

Higher growth rates and biomass productivity compared to terrestrial plants.

Have the capacity to produce energy-rich oil and carbohydrates, which can be converted to biofuels using existing technology.
