Effect of nutrient medium, initial density on the growth of microalgae chaetoceros muelleri, Tetraselmis suecica and trial biomass development under outdoor conditions in Thua Thien Hue province

Nội dung tóm tắt: This paper aims at identifying the effect of the nutrient medium and initial density on the growth of microalgae Chaetoceros muelleri, Tetraselmis suecica and performing experiments on outdoor biomass breeding under the most basic conditions. The findings showed that the F/2 medium and the Walne’ medium were the most suitable for Chaetoceros muelleri and Tetraselmis suecica, respectively. After 11 days, Chaetoceros muelleri that represented 10 % in the total culture medium reached the maximum density at (5.55 ± 0.05)×105 cells/mL with a stable balanced phase. Tetraselmis suecica that represented 15 % in total culture medium reached the maximum density at (13.48 ± 0.09)×104 cells/mL with stable balanced phase on the ninth culture day. The results of mass culture showed that after 8 culture days, Biomass Chaetoceros muelleri cultured naturally in a 50 L container reached a maximum density at (4.31 ± 0.08)×105 cells/mL, while in a 1000 L container the biomass reached a maximum density at (3.17 ± 0.10)×105 cells/mL. Tetraselmis suecica biomass reached the highest density at (14.44 ± 0.14)×104 cells/mL in the volume of 50 liters after 7 culture days. Whereas, the biomass reached (9.23 ± 0.32)×104 cells/mL in the volume of 1000 liters after 6 culture days.
