Researchers set criteria for determining best microalgae for biodiesel

In Washington, in the Journal of Renewable and Sustainable Energy, by AIP Publishing, researchers developed a methodology to analyze the properties of different species to select the best microalgae for use as an energy source by taking into account biological, economic, and environmental aspects. 

The researchers created an overall score that standardized criteria for potential large-scale cultures, covering biomass and oil production requirements, triacylglyceride content and biodiesel quality. They examined nine types of microalgae and found the native benthic diatoms H. coffeaeformis, Navicula cincta, and N. gregaria appeared to be the most promising species for biodiesel production. 

The researchers also uncovered promising new areas for further research. They found many diatom species have favorable characteristics for sustainable biofuel production and are robustly resistant to extreme environmental conditions. This species, however, has not yet generated a significant degree of scientific interest in the bioenergy field but should be at the forefront of bioprospecting efforts for biodiesel production.
