光合细菌研究进展

Research Progresses on Photosynthetic Bacteria

光合细菌分布广泛,本身无毒,富含蛋白质、类胡萝卜素等多种营养物质,得到广泛应用。光合细菌的分子生物学研究已开展了40多年,在固碳和蛋白质表达系统研究方面取得了丰硕成果。阐述了光合细菌cbb操纵子固碳的分子机制和光合细菌作为新型蛋白质表达系统的研究进展,提出了未来的研究重点,为光合细菌的综合开发和利用提供了新思路。

Photosynthetic bacteria are widespread, safe and rich in protein and carotenoids, and thus widely-used. So far molecular biology researches of photosynthetic bacteria have been performed over 40 years in wide research fields and a large number of research findings are obtained in carbon fixation and protein expression system. The present review describes the research progresses of photosynthetic bacteria in the mechanisms on carbon fixation by cbb operon and novel protein expression system. It puts forward the future research focus and supplies new insights into the comprehensive development and application of photosynthetic bacteria.
