Effect of temperature and increased concentration of CO2 on growth and photosynthetic activity of polar alga Trebouxia sp.

Original language description

Trebouxia sp., a lichen symbiotic alga, was isolated from lichen Usnea antarctica collected at James Ross Island, Antarctica. After isolation, the alga was cultivated on Bold´s Basal Medium (BBM-agar) with addition of nitrogen for 12 days. Growth of algaand its photosynthetic properties were studied in relation to increased concentration of CO2 (850?50 ppm) and two cultivation temperature (8 and 12°C). Physiological status of algae was evaluated by chlorophyll fluorescence parameters. Simultaneously, content of pigments and changes in biomass were evaluated during cultivation period. Evaluation of physiological state of Trebouxia sp. was carried out after the end of experiment. Results of chlorophyll fluorescence induction parameters and content of pigments showed that the highest efficiency of primary processes of photosynthesis was found at the treatment with elevated concentration of CO2 and temperature 12°C.
