Microalgae are considered one of the most promising feedstocks for biofuels. The productivity of these photosynthetic microorganisms in converting carbon dioxide into carbon-rich lipids, only a step or two away from biodiesel, greatly exceeds that of agricultural oleaginous crops, without competing for arable land. Worldwide, research and demonstration programs are being carried out to develop the technology needed to expand algal lipid production from a craft to a major industrial process… 
Algae for Biofuels and Energy
This book covers the key steps in the production of renewable biofuels from microalgae - strain selection, culture systems, inorganic carbon utilisation, lipid metabolism and quality, hydrogen production, genetic engineering, biomass harvesting, extraction.
Biofuels from Microalgae
Biofuels from micro algae can only become realistic if the cost of production of algae is reduced, if the produntivity of lipids in microalgae is maximized, and if besides lipids, other compounds are validated for applications for food, feed, chemistry, and materials using a microalgal biorefinery.

Towards increased microalgal productivity in photobioreactors
Two concepts of light dilution in photobioreactor design are presented to reflect how potentially higher photosynthetic efficiencies can be achieved and fast screening methods for micro algae are discussed, which can be applied to select strains with better production characteristics.
Microalgae for the production of bulk chemicals and biofuels
Production of bulk chemicals and fuels from microalgae will become economically feasible if production of algae is done on a large scale against low production costs and residual nutrient feedstocks and CO2 are done.
