Algal biofuels represent various methods to produce highly reduced hydrocarbons from carbon dioxide using solar energy as the power source and algae, typically microalgae, as the machinery. The primary driving point for photosynthesis powered biofuels is that they do not increase the net carbon content in the air; every molecule of CO2 released during combustion came from one molecule of CO2 fixed during photosynthesis. Since their energy source is sunlight, algal biofuels are considered renewable. Algae are top choices in biofuel engineering due to their far greater photosynthetic efficiency and low growth requirements. In addition, countries that lack reserves of fossil fuels may desire economic independence by reducing imports through domestic fuel product.

History

Cultivation

One of the most distinct advantages of microalgae over other photosynthetic organisms is their tolerance and/or preference for marginal water sources [1]. This means that algal biofuels won't have to compete for resrouces like fresh water and arable land with food crops, unlike biofuels derived from corn and soybeans [2].

iGEM Connection

The University of Washington's 2011 iGem Team attempted to use Fatty Acid intermediates into alkanes [3]. They used Acy-ACP Reductase (AAR) to convert long Acyl-ACPs into aldehydes, and then used Aldehyde Decarbonylase (ADC) to convert them into alkanes.
