Effect of light and nutrient limitation on lipid productivity in Chlorella kessleri for algal biodiesel production
Year: 2015
Type: conference-abstract
Abstract: Biofuels, fuels derived from biological materials, are considered an attractive alternative for fixing the ongoing energy crisis, due to their unlimited renewable resources and no net CO2 release into the atmosphere.The use of food crops such as corn, soybean, castor seeds, rapeseeds is undesirable due to the need for large cultivation areas, high loads on freshwater sources, and competition with food markets.Unicellular photosynthetic thallophytes, the microalgae, are being explored as a potential source of biodiesel, owing to their ease of cultivation, low nutrient requirements, little dependence on agricultural land, and ability to grow on waste water.Light-dependent growth is the most widely used technique for biodiesel production from microalgae.However, the inability to achieve a high biomass as a result of poor light penetration complicates the process as well as decreases the yield.Therefore, heterotrophic culture of microalgae in the dark when supplemented carbon source may be a way to overcome the drawbacks of autotrophic growth in mass culture.
