Oil algae extraction from nannochloropsis SP: a study of soxhlet extraction and ultrasonic assisted extraction

This is a study on oil extraction from microalgae for basic material of biodiesel. It was carried out by sokhlet extraction (SE) and ultrasonic assisted extraction (UAE). While the types of microalgae being studied was Nannochloropsis sp., the solvent used was ethanol. The extraction process was don...
