LED 광 배양조 디자인 개발

Marine Bio-industry is in the spotlight as the future growth industry that creates the higher-value from marine living resources. Especially, microalgae, phytoplankton that lives in the sea and river, is recently used to make high value-added products such as functional food and feed, cosmetics, medicine, seaweed pulp etc. The aim of this study is to develop a light-culture tank for microalgae cultivation using LED as light source. Till date this technique is not so popular in domestic algae industry and also very little information exist on the light-culture tank using LED as light source. In order to maintain good-growth of microalgae, microalgae must be grown in suitable light conditions viz. light source, transmission and distribution along with proper nutrients and gas (carbon dioxide and oxygen) transmission. The present work focuses on the light source as one of the various factors for microalgae cultivation, by using LED as the light source which is considered to be eco-friendly and low-cost. Further the study also explains on the design and development of light-culture tank for user convenience and for equable distribution of light inside the tank by survey of other light-culture tank and LED system used nationally and internationally. Finally, after design and manufacturing the light-culture tank, it was used for cultivation of microalgae which had a strong influence into the active growth of microalgae. This study provides good information about the increased competitiveness in investigation for microalgae cultivation that creates the market for higher-value compounds from marine living resources.
