ABSTRACT
Some photosynthetic organisms can capture atmospheric CO2 and produce a biomass, with high levels of oil. This oil is therefore considered as a renewable resource, which could be an alternative to fossil hydrocarbons. This article provides a detailed definition of the terms microalgae, oil and biofuel, and gives a brief state of the art of technologies for cultivation, harvesting, oil extraction and conversion into biodiesel fuel, from laboratory to pilot scale, highlighting the biotechnological and technological challenges that will need to be addressed in the future.
Read this article from a comprehensive knowledge base, updated and supplemented with articles reviewed by scientific committees.
