Activity of Antioxidant Enzymes of Cyanoprokaryota and Green Microalgae Cultures under Different Temperatures Conditions
ABSTRAKT
The effect of different temperatures (20, 26 and 32 °C) of cultivation on the activity of antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT), and glutathioneperoxidase (GPO) was studied in some species of Cyanoprokaryota (Aphanocapsa planctonica (G.M. Sm.) Komarek et Anagn., Phormidium autumnale (C. Agardh) Gomont f. uncinata (C. Agardh) N.V. Kondrat.) and Chlorophyta (Desmodesmus communis (E. Hegew.) E. Hegew., and Tetraedron caudatum (Corda) Hansg.). The activity of antioxidant enzymes depends on the temperature, culture age, and species. Maximal temperature (32 °C) significantly inhibited the activity of SOD, CAT, and GPO in cyanobacteria and green microalgae, especially in older cultures. It is shown that under studied conditions dynamics of the SOD and CAT activity of both Cyanoprokaryota and Chlorophyta do not coincide and mainly is in the antiphase. At 20 and 26 °C the enzymatic activity of GPO in older cultures of Cyanoprokaryota and Chlorophyta is significantly higher in comparison with the young. At the same time, at the maximal temperature (32 °C) activity of the enzyme in older cultures was almost completely inhibited.
