The study of different aspects related to the behavior of microalgae has received renewed interest due to the wide field of application of these microorganisms. Algae cultures have been principally developed as an important source of many products,such as aquaculture feeds, human food supplements, and pharmaceuticals (Pulz and Gross, 2004; Apt et al.
1999) and they have been suggested as a very good candidate for fuel production (Shenk 2008).
