Abstract

ENERGY IS ESSENTIAL AND VITAL FOR DEVELOPMENT, AND THE GLOBAL ECONOMY LITERALLY RUNS ON ENERGY THE USE OF FOSSIL FUELS AS ENERGY IS NOW WIDELY ACCEPTED AS UNSUSTAINABLE DUE TO DEPLETING RESOURCES AND ALSO DUE TO THE ACCUMULATION OF GREENHOUSE GASES IN THE ENVIRONMENT. RENEWABLE AND CARBON NEUTRAL BIODIESEL ARE NECESSARY FOR ENVIRONMENTAL AND ECONOMIC SUSTAINABILITY. BIODIESEL DEMAND IS CONSTANTLY INCREASING AS THE RESERVOIR OF FOSSIL FUEL ARE DEPLETING. UNFORTUNATELY BIODIESEL PRODUCED FROM OIL CROP, WASTE COOKING OIL AND ANIMAL FATS ARE NOT ABLE TO REPLACE FOSSIL FUEL. THE VIABILITY OF THE FIRST GENERATION BIOFUELS PRODUCTION IS HOWEVER QUESTIONABLE BECAUSE OF THE CONFLICT WITH FOOD SUPPLY. PRODUCTION OF BIODIESEL USING MICROALGAE BIOMASS APPEARS TO BE A VIABLE ALTERNATIVE. THE OIL PRODUCTIVITY OF MANY MICROALGAE EXCEEDS THE BEST PRODUCING OIL CROPS. MICROALGAE ARE PHOTOSYNTHETIC MICROORGANISMS WHICH CONVERT SUNLIGHT, WATER AND CO2 TO SUGARS, FROM WHICH MACROMOLECULES, SUCH AS LIPIDS AND TRIACYLGLYCEROLS (TAGS) CAN BE OBTAINED. THESE TAGS ARE THE PROMISING AND SUSTAINABLE FEEDSTOCK FOR BIODIESEL PRODUCTION. MICROALGAL BIOREFINERY APPROACH CAN BE USED TO REDUCE THE COST OF MAKING MICROALGAL BIODIESEL. MICROALGAL-BASED CARBON SEQUESTRATION TECHNOLOGIES COVER THE COST OF CARBON CAPTURE AND SEQUESTRATION. IN THE PRESENT STUDY BIODIESEL PRODUCTION BY MICROALGAE OIL EXTRACTED AND ITS EFFECTS ON CO2 BIOMITIGATION IS INVESTIGATED. THE POSSIBILITY OF BIODIESEL PRODUCTION BY THE OIL PRODUCED FROMDUNALILLA SALINA AND R.ORYZAE IS ALSO DESCRIBED. THE PERCENTAGE CONVERSION OF REACTION WITH 1: 1 MOLAR RATIO SHOWED 58.74% OF FREE FATTY ACIDS TO METHYLESTER OR BIODIESEL. THE REACTION WITH EXTRA SOLVENT (ACETONE) AND EXTRA METHANOL WAS REPEATED AND THE CONVERSION OBTAINED WAS 71.97% AND 90.03% OF FREE FATTY ACIDS TO BIODIESEL.
