Title: Microalgae for biodiesel and 3rd generation bioethanol: prospects and research priorities

Biography

Biography: Qian Kang

Abstract

Algae are gaining wide attention as an alternative renewable source of biomass for the production of biofuel, including biodiesel and bio-ethanol. The utilization of algal biomass is undoubtedly an eco-friendly approach towards sustainability although more research and development is needed for the efficient use of these easily cultivable microorganisms to generate biofuel. The paper reviews the current state-of-science with respect to microalgal biofuel production, with a specific focus upon the biodiesel and bio-ethanol production potential. An updated literature review reveals that different types of microalgae can be applied, although Chlorella sp. and Chlorococcum sp. are most appropriate for biofuel production and can also be used for bio-ethanol. The bio-ethanol productivity from green algae is higher than for red algae. The complete production process is analyzed from algae growth, to harvesting, and conversion into biodiesel and bio-ethanol. The use of microalgae in a hybrid objective, i.e. the treatment of wastewater and generation of raw material for biofuel, has drawn a lot of attention over the past years and is reviewed. Clearly, biofuel from microalgae, produced from natural resources (sunlight, water and O2/CO2) is widely considered to be the most sustainable option for biodiesel and associated bio-ethanol production, and priority research can enhance the further development.
