초록

광에너지를 이용하여 바이오원료 및 바이오케미컬을 생산하려는 새로운 시도가 많은 관심을 받고 있다. 특히, 광합성기작을 이용한 다양한 바이오유래 물질을 생산하려는 연구가 진행되고 있다. 본 연구에서는 광합성기작을 갖고 있는 해양 미생물인 Salinibacter ruber의 세포막에서 retinal과 salinixanthin의 작용으로 광전자를 흡수하는 역할을 하는 잔토로돕신을 수성 이상계 계면 농축법을 이용하여 효율적으로 분리하였다. 분리된 잔토로돕신을 생물학적 세포막인 레시틴으로 리포좀을 생성하여 잔토로돕신의 광전자흡수 활성을 그대로 갖는 인위적인 잔토로돕신-레시틴 리포좀을 제작하였다.

Capture and conversion of abundant solar energy using biotechnology will be essential for the development of sustainable and future energy. Photosynthesis is used for the production of biofuels such as biohydrogen. In this study, lightharvesting xanthorhodopsin consisting of retinal and salinixanthin was isolated from a photosynthetic microorganism Salinibacter ruber by aqueous two phase extraction. To stabilize the light-harvesting machine, artificial xanthorhodopsin-liposome system was reconstructed to have photoelectron absorption activity.
