An Overview of Environmental Factor’s Effect on the Growth of Microalgae
Microalgae cultivation is currently considered to a sustainable candidate for the production of biomass for biofuel feedstock. Moreover, the use of wastewater may make it more environmentally friendly. Cultivation of microalgae needs certain range condition of environmental factors such as photoperiod, light intensity, temperature, and salinity for optimal growth conditions. Many researchers have investigated ways to increase the efficiency of biomass production by designing a favorable range of environmental factors to enhance the rate of productivity. However, these environmental factors are not always suitable, as conditions for growth at an optimal level vary according to microalgae species and strain. This article presents a brief overview of the effect of environmental factors on the growth of microalgae. Optimal conditions and environmental factors for massive biomass production via microalgae cultivation are discussed.
