| description | In recent years, more attention has been paid to the use of third generation
feedstocs for the production of biodiesel. One of the most promising sources
of oil for biodiesel production are microalgae. They are unicellular or
colonial photosynthetic organisms, with permanently increasing industrial
application in the production of not only chemicals and nutritional
supplements but also biodiesel. Biodiesel productivity per hectare of
cultivation area can be up to 100 times higher for microalgae than for oil
crops. Also, microalgae can grow in a variety of environments that are often
unsuitable for agricultural purposes. Microalgae oil content varies in
different species and can reach up to 77% of dry biomass, while the oil
productivity by the phototrophic cultivation of microalgae is up to 122
mg/l/d. Variations of the growth conditions and the implementation of the
genetic engineering can induce the changes in the composition and
productivity of microalgal oil. Biodiesel from microalgae can be produced in
two ways: by transesterification of oil extracted from biomass or by direct
transesterification of algal biomass (so called in situ transesterification).
This paper reviews the curent status of microalgae used for the production of
biodiesel including their isolation, cultivation, harvesting and conversion
to biodiesel. Because of high oil productivity, microalgae will play a
significant role in future biodiesel production. The advantages of using
microalgae as a source for biofuel production are increased efficiency and
reduced cost of production. Also, microalgae do not require a lot of space
for growing and do not have a negative impact on the global food and water
supplies. Disadvantages of using microalgae are more difficult separation of
biomass and the need for further research to develop standardized methods for
microalgae cultivation and biodiesel production. Currently, microalgae are
not yet sustainable option for the commercial production of biodiesel. First
of all, the price of biodiesel from microalgae is still higher than the price
of diesel due to high production costs. [Projekat Ministarstva nauke
