Low-temperature polar microalgae for biomass production

The polar microalgae represent a very important biotechnological potential. Selected strains will be cultivated in different cultivation modes and their growth rates will be compared to results of laboratory cultivations. The biomass of strains cultivated in Svalbard will be used for screening for biotechnologically valueable compounds.

Polar microalgae are prospective for low-temperature biotechnology development in the Polar Region, since these technologies are necessary for inevitable for human expansion there, especially in case of the Arctic. The algal biotechnologies could, and in the future definitely will, play crucial role in carbon scavenging, waste water treatment and biomass production for aquaculture or for biotechnologically valueble compounds. Suitable strains should be adapted to broad temperature and light tolerance, and to minimum nutrient requirement. Therefore, different polar microalgal strains are being screened for their growth requirements for temperature, light and nutrients in laboratory conditions, and mathematical models are been developed for each strains. The strains meeting the criteria will be cultivated in polar summer condition to track the response to the real in situ conditions and to compare ot to the laboratory experiments results. The algal biomass producd in situ will be screened for the botechnologically valuable compounds.
