摘　　要：The growing demand for energy and the negative environmental impacts of fossil fuel use are triggering global searches for a renewable and eco-friendly alternative biofuel. Microalgae are considered as one of the most promising feedstocks for biofuel production, due to many advantages including cultivation </span><span><span style="font-family:Verdana;">in non-arable land and being able to grow in wastewater or seawater. That is why;microalgae-based biofuels are regarded as one of the best candidates to replace fossil fuels. There are two main types of microalgae cultivation systems: Open Raceway Ponds and Closed </span><span style="font-family:Verdana;">Photobioreactos</span><span style="font-family:Verdana;"> (PBRs). Due to some limitations in Open Raceways, PBRs have become the most favorable choice for biofuel producers, ev</span></span><span style="font-family:Verdana;">en though it is costly. To make the process viable, the growth of microalgae for biofuel production should be </span><span style="font-family:Verdana;">cost</span></span><span style="font-family:Verdana;">-</span><span style="font-family:Verdana;">effective</span><span style="font-family:""><span style="font-family:Verdana;">.
