Microalgae have recently attracted considerable interest worldwide, due to their extensive application potential in the renewable energy, biopharmaceutical, and nutraceutical industries. Microalgae are renewable, sustainable, and economical sources of biofuels, bioactive medicinal products, and food ingredients. Several microalgae species have been investigated for their potential as value-added products with remarkable pharmacological and biological qualities. As biofuels, they are a perfect substitute to liquid fossil fuels with respect to cost, renewability, and environmental concerns. Microalgae have a significant ability to convert atmospheric CO2 to useful products such as carbohydrates, lipids, and other bioactive metabolites. Although microalgae are feasible sources for bioenergy and biopharmaceuticals in general, some limitations and challenges remain, which must be overcome to upgrade the technology from pilot-phase to industrial level. The most challenging and crucial issues are enhancing microalgae growth rate and product synthesis, dewatering algae culture for biomass production, pretreating biomass, and optimizing the fermentation process in case of algal bioethanol production. The present review describes the advantages of microalgae for the production of biofuels and various bioactive compounds and discusses culturing parameters.

“…Marine algae are responsible for about 35-40% of carbon fixation in nature. They have been cultivated and used by human being as sources of proteins, oils, vitamins, chemicals, fertilizers, fuel and bioremediation (Qari et al, 2017;Chen et al, 2018).…”

“…According to Qari et al, (2017), the most effective cultivation method of algae for biofuel production is the heterotrophic cultivation, where the algae convert the supplied nutrients into their biomass in a very little time. Algae can be cultivated in natural Novel Research in Microbiology Journal, 2019 water bodies such as lakes, ponds, or lagoons.…”

“…The harvesting and conversion of algal oil into biofuel cost the most. Accordingly, there is a need to develop genetically improved algal strains and harvesting technologies, to decrease the biofuel production costs to 0.013 $/ gallon of gasoline (Qari et al, 2017).…”

“…In reference to Shuba and Kifle, (2018), life cycle assessment studies (LCA) revealed that the use of the third generation of biofuels such as microalgae as fuel sources can overcome the drawbacks related to the former generations of biofuel. Chen et al, (2015); Qari et al, (2017) previously documented that microalgae are capable of storing high lipid contents (up to 80%), thus shows their potential as a renewable energy source for sustainable fuel production. Their lipid storage capacity is 100 times more than the conventional oil crops such as; Brassica napus and Jatropha curcas.…”

The shortage of fuel in the near future and the change in climate due to greenhouse gases are serious challenges of a global concern, thus it is imperious to explore new sustainable ways to overwhelm these challenges. The need of a new sustainable energy sources has increased the importance of the third generation biofuel produced from non-food stocks such as algae, which possibly represent a great opportunity in the long term. The major challenge of the algae based bio-fuel production is their extraordinary cultivation costs, which make their commercialization economically infeasible. Algal spp. especially Chlorella spp. are capable of thriving in waste water and can accumulate high lipid contents. The aim of the current review was to highlight the possible integration of waste water treatment and algae based bio-fuel production, as a sustainable option for cost effective bio-fuel production along with lower environmental impact.
