TEMPERATURE ACCLIMATION AND THE FATTY ACID COMPOSITION OF AN ANTARCTIC GREEN ALGA CHLORELLA (16th Symposium on Polar Biology)
Antarctic green alga Chlorella vulgaris strain SO-26 cells cultured at 20℃ photosynthesize between 0-35℃, with a maximum rate at 20℃, while cells cultured at 10℃ show a shift of the optimum to about 2 to 3℃ lower and show higher activity than cells cultured at 20℃. Mesophilic alga Chlorella sorokini...
