Producing crude oil from algae: Difference between revisions

Biofuels are an alternative to fossil fuels that are produced from fats derived from living organisms. One source of biofuel that is being explored more thoroughly in recent years is microalgae. The bio substance can be turned into crude oil, which can then be used to create biodiesel, biobutanol, biogasoline, methane, ethanol, or jet fuel. (http://en.wikipedia.org/wiki/Algae_fuel)  

In 1942, European scientists Richard Harder and Hans von Witsch proposed the mass cultivation of diatoms to produce fat, which was urgently needed because of World War II. (Liang) Government researchers began exploring algae as a source of fuel in 1978 and continued experiments through 1996. (http://en.wikipedia.org/wiki/Biofuel)  

Algae can be grown under multiple conditions, including those unfavorable to other plants. It can bloom in places where salty water, excessive sun exposure, and lack of vital nutrients inhibit growth of other crops. But the higher the concentration of algae cells, the lower the ability to absorb light. In heterotrophic conditions, the algae can use sugars, organic acids, and other organic carbons as carbon sources, replacing the need for light.
