Algal biotechnology is drawing increasing interest due to its potential as a source of valuable pharmaceuticals, pigments, carbohydrates, and other fine chemicals. Recent development in various algal biotechnology found microalgal mass culture can be a useful solution in treatment of
wastewater, fixation of carbon dioxide and production of biofuel. Furthermore, the fact that microalgae can conquer the top three environmental problems in a simultaneous manner is even more exciting.
(i) Green house gases such as CO2 in the atmosphere became a serious problem for the whole mankind. One of the possible solutions is a biological CO2 fixation using the photosynthesis of
microalgae.
(ii) Microalgae have been utilized for several decades for the treatment of municipal and other wastewaters. The removal of heavy metals and/or residual nutrients, specifically N and P, has also been studied with a variety of processes.
(iii) Renewable, carbon neutral, liquid fuels for the transportation sector are necessary for environmental and economic sustainability. Approaches for making microalgal biodiesel economically competitive with petrodiesel would be possible in the near future.
In this presentation, various photobioreactors and culturing facilities will be presented and analyzed.
