“…), the influence of the methyl group was found to affect the yield of biodiesel. The H2SO4 yielded 1.23%, which is higher than the 0.87% yielded by the HCl catalyst (Mansur et al, 2017). The findings of Kim et al (2015) and Mansur et al (2017) suggest that microalgae species and process conditions influence the selection of catalysts for transesterification.…”

Microalgae are becoming sustainable alternative feedstocks to food crops for biodiesel production which can also solve the problems associated with the use of fossil fuels. However, several challenges about microalgae’s cultivation, harvesting, pre-treatment and extraction processes as well as the technology of biodiesel production affect its sustainability. This study proffers solutions to these challenges and recommended that hybrid culture systems with genetically engineered microalgal species would overcome the challenges of cultivation. The coagulation/flocculation method was adjudged the best harvesting process of the microalgae for its sustainability for biodiesel production. The pre-treatment by ultrasound coupled with enzymatic extraction was suggested best, due to their numerous advantages over other methods. A novel integrated ultrasound-enzyme-enzyme in-situ pre-treatment-extraction-transesterification design is considered a sustainable approach to utilising microalgae biomass for biodiesel production. The study concludes that the microalgae biomass is more than sufficient to meet the global energy demand and can be economically harnessed as a sustainable feedstock for biodiesel production. HIGHLIGHTS •Microalgae contain sufficient characteristics for their sustainability for biodiesel production.• Implementation of genetic strategies of microalgal species by cultivating in a hybrid system is the key to microalgae sustainability.• Harvesting of microalgae by coagulation/flocculation method would promote its efficient lipid recovery.• Microalgae are novel feedstocks with a rigid cell wall, its lipid extraction requires the use of effective and efficient pre-treatment.• The ultrasound-enzymatic extraction and enzymatic transesterification in an in-situ process can sustainably utilise microalgae biomass for biodiesel production.

“…Microalgae consist of complex lipids ( for instance 56 mass percentage of total lipids of Chlorella vulgaris has 18 carbon in fatty acid chain [142]). Acetone ( as organic solvent) cannot extracted this type of lipids without helping of catalyst [143] or cosolvent [144] . Thus, it is assumed that the lipids have not been extracted in pigment extraction.…”
