Biodiesel is a mixture of monoalkyl esters of long chain fatty
acids [fatty acid methyl esters (FAME)], which can be obtained
from different renewable lipid feedstocks and biomass. It can
be directly used in different diesel engines (Clark and Deswarte,
2008; Demirbas, 2009). Studies to explore the microalgae as feedstock
for the production of liquid fuels had been started for
the mid-1980s. In order to solve the energy crisis, the extraction
of lipids from diatoms was attempted by some German
scientists during the period of World War-II (Cohen et al.,
1995). The higher oil yield in algal biomass as compared to oil
seed crops makes the possibility to convert into the biodiesel
economically using different technologies. A comparative study
between algal biomass and terrestrial plants for the production
