“…At present, microalgal‐based biodiesel is the most promising bioenergy source, with its characteristics including high biomass and lipid productivity, rapid growth rate, short harvest cycles, less land usage and capability to grow on land which is not suitable for other crops . Deep sea water (DSW) has long been recognized to benefit fisheries, medicine , cosmetics, agriculture and energy generation . DSW, also referred as deep ocean water (DOW), constitutes 95% of the ocean, and is located underneath the thermocline (typically 200 m below the ocean surface), where the temperature drops rapidly along with depth.…”

“…DSW, also referred as deep ocean water (DOW), constitutes 95% of the ocean, and is located underneath the thermocline (typically 200 m below the ocean surface), where the temperature drops rapidly along with depth. The unique properties of DSW are as follows: (i) low temperature; (ii) abundant in nutrients; (iii) hosting less pathogens compared to the surface; and (iv) very stable due to its aged state .…”

Microalgae-based biodiesel has been recognized as a sustainable and promising alternative to fossil diesel. High lipid productivity of microalgae is required for economic production of biodiesel from microalgae. This study was undertaken to enhance the growth and oil accumulation of an indigenous microalga Chlorella sorokiniana CY1 by applying engineering strategies using deep-sea water as the medium. First, the microalga was cultivated using LED as the immersed light source, and the results showed that the immersed LED could effectively enhance the oil/lipid content and final microalgal biomass concentration to 53.8% and 2.5 g/l, respectively. Next, the semi-batch photobioreactor operation with deep-sea water was shown to improve lipid content and microalgal growth over those from using batch and continuous cultures under similar operating conditions. The optimal replacement ratio was 50%, resulting in an oil/lipid content and final biomass concentration of 61.5% and 2.8 g/l, respectively. A long-term semi-batch culture utilizing 50%-replaced medium was carried out for four runs. The final biomass concentration and lipid productivity were 2.5 g/L and 112.2 mg/L/d, respectively. The fatty acid composition of the microalgal lipids was predominant by palmitic acid, stearic acid, oleic acid and linoleic acid, and this lipid quality is suitable for biodiesel production. This demonstrates that optimizing light source arrangement, bioreactor operation and deep-sea water supplements could effectively promote the lipid production of C. sorokiniana CY1 for the applications in microalgae-based biodiesel industry.

“…Deep sea water, with its unique chemical composition, has been shown to have therapeutic effects not only in the treatment of skin conditions such as atopic eczema/dermatitis syndrome, but also in the prevention of life-threatening diseases, including cancer, diabetes, obesity, hypertension, hypercholesterolemia, and atherosclerosis (Nakagawa et al, 2000;Kimata et al, 2002;Yoshioka et al, 2003;Miyamura et al, 2004;Shon et al, 2008;Hwang et al, 2009). Some countries, including the United States, Korea, Japan, and Taiwan, have succeeded in using DSW as a natural resource for domestic industries (Nakasone and Akeda, 1999;Liu et al, 2008). Korea has commercialized the use of DSW in areas such as energy production, medicine, cosmetics, aquaculture, agriculture, and food and beverage production.…”

Deep sea water (DSW) has health benefits and is widely used as food supplement; however, its effect in fermented products has not been explored. Here, we investigated the effect of DSW-containing yogurt on health-related serum parameters and intestinal microbiota in mice. Animals were assigned to 3 feeding groups, which received water (control), normal yogurt (N-yogurt), or DSW-containing yogurt (DSW-yogurt) with a basal diet. Mice were killed at wk 4 or 8 of feeding and analyzed for serum parameters and microbial population in the small intestine. Both yogurt groups demonstrated increased populations of intestinal lactic acid bacteria compared with the control group. The activity of serum aspartate aminotransferase and alanine aminotransferase was markedly decreased in the DSW-yogurt and N-yogurt groups, and triglyceride level tended to be lower in the DSW-yogurt group compared with that in the control mice. Furthermore, the DSW-yogurt group showed a more significant decrease in the ratio of total cholesterol to high-density lipoprotein-cholesterol than did the N-yogurt group. These findings suggest that DSW supplementation of yogurt can increase its beneficial effects on lipid metabolism.

“…The plan was approved by the Executive Yuan in January, 2006. In order to promote DSW cluster industries, WRA set up the "DSW resource technology development research center," in charge of research and technology for the DSW industry in Taiwan (Liu, Hwung, Yu, & Kao, 2008). Under the umbrella of "Challenge 2008: National Development Plan" launched by the Executive Yuan, with the basic strategy of "globalized link, local action," the DSW Government Entities *Integrate resources of promotion *Survey fundamental and special oceanic resources *Provide nation-owned land for rent *Support financially scientific projects *Enact (update) concerned laws and regulations.…”

The deep sea water (DSW) industry has a great commercial potential for the global health tourism market. This study aims to investigate the successful relationships between stakeholders with a focus on the role of the government. Two surveys were conducted on the east coast of Taiwan to discover if the local governments were willing to give any assistance of the development of the DSW industry. The results of the study revealed that the first priority was the installation of a thalasso spa in Hualien, eastern Taiwan. Taiwan Government must consider that the opening of three similar facilities close together will need careful planning and study of the market size. The study suggests establishing a government-owned DSW Research & Development Park and thalasso spa near the three private sectors to balance the fierce competition among the three private companies.
