The present invention relates to the preparation of carboxylic acid ester compounds, biodiesel (B), from microalgae, for use as biofuel in compression ignition. This objective is achieved by means of a wet microalgae biomass (MU) hydroesterification process comprising a hydrolysis step and an esteri...
