| Abstract:
The versatile use of biomass and specific products from microalgae make them attractive for several applications in industry and economy. However, a commercial use of advanced systems is limited by the efficiency of product yields, extraction of sensitive products and high costs during processing. High expenses are caused by nutrients, energy-intensive cultivation (defined temperature and light regime) and preparation of the microalgae like drying and cracking of the cell wall. With these problems in mind, different researchers are working on methods to optimize the systems to make microalgae based applications economically usable. The focus of the presented concept is to enhance the biosynthesis of several metabolites as well as the growth rate by a high-frequency electromagnetic radiation treatment. At the same time the risk of contamination in the photobioreactors is reduced. We show, that high frequency electromagnetic fields can be used for small biological systems to stimulate various processes in the cells. | |
