1. Su , Chong-bin. Biomass Productivity and Chlorella Extraction Enhanced by Ultrasound Exposure and Light.

Degree: Master, Mechanical and Electro-Mechanical Engineering, 2014, NSYSU

In the wake of highly development in the physical civilization and the prosperity of industry and commerce, humans are confronting with huge pressure on energy and environments, whereas the natural resources will be eventually depleted. Meanwhile, due to carbon dioxide emissions greatly increased in recent years, which results in global warming and brought to a negative greenhouse phenomenon. Because of growing up by the algae itself, it has the ability to perform photosynthesis and convert into compounds and store in the form of lipid. The final step of when the biolipid converted into the biodiesel, which is a way to reduce carbon dioxide emissions and can be considered as inexhaustible alternative energy. Hence, attempts have been made on this study via using Chlorella sp. and Nannochloropsis oculata to investigate the influence of different culture media and cultured way on algae, and then evaluate the feasibility of mass production in indoor farming. In the process of study the effect of biomechatronic in ultrasonics and LED lights will also take into account, which affect the growth of algae and lipid production. The results showed that the lowest culture concentration of Chlorella sp. is 3.2Ã108 cells/c.c. under the volume 300 ml by shock, and it can grow 1.76 times after 5 days, moreover, the optimum temperature for algae growth is 35°C. The Taguchi method results showed that the best algae experiments growth increased by 150.34 times in five days. The experiment with ultrasound has increased by 15.9 % as compared with that of without ultrasound. With regard to the optimum extraction experiment, Chlorella can be extracted 0.18 g lipid per gram shortly after 5 days. The experiment with ultrasound has increased by 19.1 % as compared with that of without ultrasound. This study can apply to algae growth and bio-energy. With the improvement of optimized process to increase biomass yield and lipidâs production, it is possible to establish the renewable energy production systems for sustainable development and environmental protection.
