Biodiesel production using Chlorella sorokiniana a green microalga

Abstract

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.
