Ultrasound assisted extraction of carbohydrates from microalgae as feedstock for yeast fermentation

- Carbohydrates from microalgae can be a promising feedstock for yeast culture to produce biofuels.
- Pretreatment of microalgae and carbohydrates extraction from algal cell were performed.
- Four factors of ultrasound assisted extraction were examined by fractional factorial design.
- Refined model was confirmed as a good fitting model via analysis of variance (ANOVA).
- Yeast biomass of the group with glucose from microalgae was much higher than that of control group.
