• Efficiency of Sodium Hydrogencarbonate as a Carbon Source for Growth of a Unicellular Alga, Nannochloropsis sp.

抄録

The efficiency of bicarbonate addition on the growth of Nannochloropsis sp. was investigated by measurement of cell volume and cell density increment after addition of sodium hydrogencarbonate. In measurement of cell volume increment, it increased rapidly by the addition of the sodium hydrogencarbonate, however, little or no increase of the cell volume was obtained in the control treatment. In the latter case, dissolved inorganic carbon (DIC) concentrations during the light photoperiod were determined to be lower than 15 ppm (as CO₂) on average. In measurement of cell density increment, transparencies of Nannochloropsis sp. culture water were 60.7, 51.7, 46.8, and 47.2 % under DIC concentrations of 15, 20, 55, and 110 ppm, respectively, at 08: 00 on the 3rd day after initiation of culture. Masses of Nannochloropsis sp. cells attached on the bottom and side of culture vessels at DIC concentrations of 55 and 110 ppm in the late light period of the 3rd day. It was suggested that an appropriate concentration for cell density increment was existed between 20 and 55 ppm.
