Abstract


Increasing energy needs cause diminishing energy resources. This encourages the searchfor renewable energy sources to anticipate scarcity. One of the new energy source is microalgae.Microalgae have a high variation of species and have a great potential to be developed as foodand other chemical products. Microalgae has been developed as a potential source of biodieselto replace petroleum fuels derived from foss ils. Of several microalgae s pecies studied,Botryococcus braunii produces the largest oil content, i.e. 75% dry weight. This paper describessteps of producing oil from B. brauniiwhich includes preparation of microalgae biomass,biomass harvesting, and extraction of oil. Oil content of B. braunii is composed mostly ofhydrocarbons (± 15–76% by dry weight), called botryococcene. This type of hydrocarbon ispotential as an energy source of biodiesel.
