Abstract

Cyanobacteria are more amenable microbial forms to genetic manipulation for installing biodiesel producing chemical pathways. These organisms have been shown to be highly tolerant to the introduction of foreign genes. Microalgae which include algal strains, diatoms, and cyanobacteria have been found to contain high levels of lipids - over 30% and upto 75%. Due to the high lipid content, these microalgal strains are of great interest in the search for sustainable sources for the production of biodiesel. The potential of this cyanobacterial fuel is the primary advantage of biodiesel that it is one of the most renewable fuels and non-toxic and biodegradable. It is powerful alternative transportation fuels as it can not only be used in existing diesel engines without modification, but also highly suitable for blending in at any ratio with petroleum diesel.
