Overlooked microalgae gets thumbs up for biodiesel use

A study in Spain has pinpointed dinoflagellate microalgae as an ‘easy and profitable way’ of creating biodiesel.

The research was led by scientists from the Universitat Autònoma de Barcelona (UAB), in collaboration with the Spanish National Research Council, and claims that the oft ignored type of marine algae is suitable for cultivation with biodiesel in mind.

Over the course of four years tests were carried out in natural conditions within exterior cultures, with no artificial light or temperature control, and subject to seasonal fluctuations.

‘If we make simple adjustments to completely optimize the process, biodiesel obtained by cultivating these marine microalgae could be an option for energy supplies to towns near the sea,’ Sergio Rossi, a researcher at the UAB, was quoted as saying.

Possible adjustments scientists highlighted included the reusing of leftover organic pulp, the use of air pumps and more efficient cultivation materials.
