碩士 / 國立臺灣海洋大學 / 水產養殖學系 / 101 / Macroalgae materials of Ulva fasciata, Gracilaria tenuistpitata, and Sargassum crassifolium, and microalgae materials of Nannochloropsis oculata, Chlorella pyrenoidsa, Chlorococcum sp., and Botryococcus braunii were used to assess the capacity of fixing carbon dioxide, and their biomass conversion rates, at indoor and outdoor, areas respectively. In the present study, the NDIR CO2 meter was used to estimate the CO2 concentration in an algae culture closed system. Which can directly determine the capacity of algae CO2 uptaking. Those algae were cultured for a long period and then evaluated their biomass. It is found S. crassifolium and B. braunii cultivated at outdoor were affected by temperature more than light intensity. The CO2 absorption rates of indoor samples, such as S. crassifolium was 26.414 ± 2.414 mg CO₂/g/hr、B. braunii was 119.944 ± 19.341 mg CO₂/g/hr, and were better than those of outdoor samples, such as S. crassifolium was 22.65 ± 3.43 mg CO₂/g/hr、B. braunii was 94.065 ± 14.946 mg CO₂/g/hr. In contrast, outdoor samples of U. fasciata, G. tenuistpitata, N. oculata, C. pyrenoidsa, and Chlorococcum sp. were more affected by light intensity than temperature. And their CO2 absorption of U. fasciata was 30.887 ± 4.123 mg CO₂/g/hr、G. tenuistpitata was 27.627 ± 3.046 mg CO₂/g/hr、N. oculata was 260.436 ± 121.376 mg CO₂/g/hr、C. pyrenoidsa was 109.324 ± 1.829 mg CO₂/g/hr、Chlorococcum sp. was 132.27 ± 7.229 mg CO₂/g/hr, which were better than those of indoor samples ,such as U. fasciata was 24.375 ± 1.339 mg CO₂/g/hr、G. tenuistpitata was 12.345 ± 0.865 mg CO₂/g/hr、N. oculata was 105.722 ± 30.663 mg CO₂/g/hr、C. pyrenoidsa was 84.409 ± 17.593 mg CO₂/g/hr、Chlorococcum sp. was 69.773 ± 10.145 mg CO₂/g/hr. Biomass conversion rates of U. fasciata which cultivated at indoor was the result of 1 g dry weight uptaking 244.795 ± 43.584 g CO₂, which is better than they were cultivated at outdoor which 1 g dry weight had uptaken 235.024 ± 33.201 g CO₂. Biomass conversion rates of N. oculata which cultivated at indoor which 1 g dry weight had uptaken 149.765 ± 75.743 g CO₂, which is better than they were cultivated at outdoor of 1 g dry weight uptaking 127.572 ± 104.841 g CO₂. The rate of CO2 absorption of U. fasciata cultured in the 80 g/2 L density was the best at outdoor among the other of macroalgae. N. oculata had the best rate of CO2 absorption among the other of microalgae when cultivated at indoor. U. fasciata also had the best biomass conversion rates.
