Integration process of biodiesel production from filamentous oleaginous microalgae Tribonema minus

- Biodiesel production from filamentous microalgae Tribonema sp. for the first time.
- Microalgal cells were successfully harvested by flotation without any flocculants.
- Lipids were extracted from wet pastes based on subcritical ethanol extraction.
- Acid-alkaline catalytic conversion was applied to produce microalgal biodiesel.
