New sustainable
scientific solutions are needed to increase the
production of biofuels; minimize negative impact on
environment or food supply; and to use less energy to
grow, extract and burn fuels than total energy they
supply. Algae are among the most promising and
renewable non-food-crop-based alternative. They
possess several characteristics that could propel them
to the forefront of the renewable fuels industry and
provide sustainable solution for energy crisis, air
pollution and climate. Compared with terrestrial
plants, algae have a high oil content and growth rate;
mass algal cultivation can be performed on
unexploited lands using saline water in arid regions,
thus avoiding competition for limited arable lands3.
