Conclusion
Producing biodiesel from algae has been touted as the most efficient
way to make biodiesel fuel. Algal-oil processes into biodiesel
as easily as oil derived from land-based crops. The difficulties in
efficient biodiesel production from algae lie not in the extraction
of the oil, but in finding an algal strain with a high lipid content
and fast growth rate that is not too difficult to harvest, and a
cost-effective cultivation system (i.e. type of photobioreactor) that
is best suited to that strain.
Algae are the fastest-growing plants in the world. Microalgae
have much faster growth-rates than terrestrial crops. The per unit
area yield of oil from algae is estimated to be from 18,927 to
75,708 l per acre, per year; this is 7–31 times greater than the next
best crop, palm oil 2404 l.
Algae are very important as a biomass source. Different species
of algae may be better suited for different types of fuel [11]. Algae
can be grown almost anywhere, even on sewage or salt water, and
does not require fertile land or food crops, and processing requires
