Freshwater microalgae (phytoplankton) are worldwide in their distribution, and they play the most important role in the biological balance of internal water bodies. Because they are unpretentious with respect to ambient environment conditions, the microalgae can actively propagate thus bringing either harm or benefit. For example, in the period of their active growth, the microalgae substantially hamper the use of surface water for potable water and industrial water supply and complicate the operation of the open systems of water recycling [1]. On the other hand, microalgae can serve as a rich source of fodder and chemical raw materials. In particular, they are suitable for the production of thirdand fourth-generation biofuels [2]. The attractiveness of microalgae for fuel production is due to the fact that their cultivation does not require extensive land sections; in this case, a large volume of biomass is reproduced at a high rate.
