• MED-ALGAE (2011-2014) is a new technology
project which can contribute to the goals of the
EU strategy on "Climate change and energy".
• It is financed by ENPI CBCMED: CROSS BORDER
COOPERATION IN THE MEDITERRANEAN.
• The development of microalgae-based biodiesel
production and other valuable products in six
Mediterranean countries (Cyprus, Egypt, Greece, Italy,
Lebanon and Malta).
• The current level of technology, the relevant market
structure, and the governmental and environmental
boundaries will be mapped in the participating
countries, in order

• Photosynthetic microbes with high efficiency
compared to the terrestrial plants
• Convert solar energy to valuable compounds.
• Non-edible
• Have Short life cycle
• Produce 10-20 times higher yield of oil
compared to vegetable oils.
• Cultivated in marginal land under harsh
conditions
• Need a minimal input requirements

Chemically, biodiesel is
composed of a mixture of
methylated, or ethylated fatty
esters

• Results shows Concentration of saturated
fractions is less than 20%.
• The presence of saturated fractions of C18:2,
C16:0 & C18:0 give good cetane no” and also
C16:1 & C18:1 with high proportion
• C20 acids represent more than 43%. Could affect
negatively on Biodiesel quality.
• This study showed highly yield biomass in
photobioreactor compared to flask cultivated alga with
Biomass 3.3 (g/L) and growth rate of (1.5/day).
is described as a good source of high
valuable compounds as it have Carbohydrates,
Pigments, Ashes and proteins
• Finally,
algae are promising
producers of biofuel precursors and nutraceuticals and
are also commercially cultivated for aquaculture feed
