Abstract

Microalgal biodiesel is considered an alternative to fossil fuel and also potentially reduce the introduction of new CO2 by displacing fossil hydrocarbon fuels. Nowadays, researching on renewable energy is mainly focus on biodiesel from microalgae due to their fast growth rates and high-yield production. In order to improve this field in Vietnam, we isolated some local species and used rapid screening method for lipid production in microalgae based on Nile Red fluorescence. Futhermore, providing a reference for the future biodiesel production using these microalgal species, we also determined lipid contents of these species ranged from 8.89% to 29.12% in natural cuturing conditions by soxhlet and Bligh & Dyer methods.
