Abstract
Summary
Nowadays, the world population has rapidly increased, resulting in rising demand for fossil fuels. However, they are not long-term sustainable energy resources. Their consumption can cause the emission of greenhouse gases, and resulting in global warming. Therefore, many researchers currently are concentrating on environment-friendly biofuel production for alternative energy sources. Sustainable renewable energy sources will play an important role in the world’s future energy supply Among the existing renewable alternative fuels resources, algae have raised great interest.
Using wastewater to culture microalgae appears to be an attractive and economical alternative. Normally, secondary and tertiary wastewaters contain a significant amount of nitrate and orthophosphate which are not removed during primary treatment. These nutrients can be used to culture microalgae, and at the same time microalgae will play an important role as a reagent to purify the wastewater. Hence, culturing of microalgae in wastewater does not only offer an inexpensive alternative to the conventional method of wastewater treatment but can also substantially reduce the need for chemical fertilizers and to grow microalgae. The use of microalgae for wastewater treatment has been employed for decades, as a low-cost process, especially in areas with increased ambient temperature and adequate sunshine throughout the year. For the economic production of microalgal biodiesel, maximum lipid productivity should be achieved. It can be possible by selecting suitable strains and culture conditions for enhancing the growth rate as well as lipid content. The current study was conducted to screen some isolated native microalgae strains with great potential for wastewater treatment, biomass production, and high lipid content.
