Biodiesel Properties of Two Strains of Cyanobacteria

Vast potential of Cyanobacteria as the most efficient primary producers makes them to become one of the most important alternative energy sources.Properties of the biodiesel obtained from Synechococcus sp and Synechocytis sp were observed during present research work.A comparative analysis of the Physical and Chemical properties of biodiesel obtained from Cyanobacteria and diesel fossil fuel were also conducted during present research study.The Synechoccus strain of Cyanobacteria had exceptionally high CN with values over 60. The lack of polyunsaturated fatty acids in the Synechococcus strain OS values of zero is surprising. It is also observed that the Synechococuus is most suited with cold weather with lower CFPA values. The values for density, viscosity and flash point remained higher in biodiesel as compared to diesel fuel. But heating value and HC ration remain almost similar in both biodiesel and diesel fuel. Thus, it became clear that biodiesel have properties superior than diesel fuel. The results of this study indicates that biodiesel have prospect to be used in place of fossil fuel.
