Biodiesel production using Chlorella sorokiniana a green microalga

Several commercial applications of microalgae are identified. They can be
used to enhance the nutritional value of food owing their chemical composition, they play
a crucial role in aquaculture and they can be incorporated into cosmetics. Currently, they
are cultivated as a source of renewable energy. Indeed, biodiesel, one form of biofuels
can be produced by microalgae. This biofuel has attracting increasing attention
worldwide as a clean energy for the future to substitute conventional fuel. However, their
production derived from conventional ways that are so expensive and polluant because
they used fossil fuels and oilseeds (vegetable oils) or animal fats. In this paper, wild/type
strains of chlorella “green microalgae” isolated from Algerian Sahara soil are tested for
their ability to produce biodiesel. The results show that Chlorella sorokiniana strain Ce,
under different culture conditions, accumulates some fatty acids which make the most
suitable for the production of good quality biodiesel.
