Optimising extraction of microalgal oil using accelerated solvent extraction by response surface methodology

The extraction of oil from biomass is one of the most important aspects in the harvesting of microalgae for the production of oil. Efficient extraction technique is important for the quantification of oil content in biomass. Solvent extraction is typically employed for the extraction of oil. Acceler...

This study showed an improvement in the oil yield using the optimum condition for ASE, where the optimum condition resulted in 1.34 fold increases in oil yield from the control run.
