Microalgae use sunlight to produce TAGs and starch, and their biomass productivity greatly exceeds the
best producing crops. In addition, some of the microalgae are also capable of producing hydrogen-a
fuel that liberates a large amount of energy per unit mass. Microalgae biofuel can be produced on nonarable land, using for this purpose saline and wastewater streams. In this way the production of biofuel
by algae will allow arable land to remain available for cultivation of crops, thus avoiding the adverse
impacts on food supplies. For these features, microalgae have been considered a promising platform to
produce of biofuels. However, it is of critical economic importance-for the practical use of microalgae
as source of renewable energy, to achieve a significant improvement in the efficiency of biofuel
production. Nowadays, with genome sequence data and a wide variety of genetic tools and powerful
analytical techniques available, new genetic engineering modifications can be accomplished to exploit
marine algae as efficient sources of biofuels if protocols for chloroplast and nuclear transformations,
and stable expression of genes are developed for species of interest. Such modifications might include
accurate reprogramming and manipulation of metabolic pathways, combined with strategies to overcome
the limitations of CO2 fixation and light capture, which are crucial to optimize biomass productivity.
