Biocomponent-based microalgal transformations into biofuels during the pretreatment and fermentation process.

•Algal biocomponents has an influence on pretreatment and fermentation efficiency.•Highest biofuels yield (0.44–0.55 g/g) was obtained from Pseudochlorella sp.•Cell wall thickness dependent on bioconstituents and affected biofuels yield.•Highest total energy recovery (42%) was achieved using suitable Pseudochlorella sp.
