Ren Min Ri Bao· 2025-11-25 23:04
"十五五"规划建议提出,"完善新型举国体制,采取超常规措施,全链条推动集成电路、工业母机、高 端仪器、基础软件、先进材料、生物制造等重点领域关键核心技术攻关取得决定性突破。"二氧化碳的 生物转化,是生物制造领域极具潜力的方向。二氧化碳是生物固定和转化的原料,是全球碳素循环的重 要参与者,其转化的有机物支撑着整个食物链。通过生物技术,二氧化碳可以"变身"为淀粉、蛋白质、 燃料乃至可降解塑料。 人工合成淀粉样品 网友:我最近看到新闻,研究人员在尝试直接捕集海水中的二氧化碳,并合成为可生物降解的塑料。这 是不是属于"生物制造"的范畴?二氧化碳还能转化成什么? 编辑:没错,你提到的正是当前科技前沿热点——二氧化碳不仅是温室气体,更是潜在的"碳资源"。 本期"瞰前沿",我们邀请中国科学院天津工业生物技术研究所研究员蔡韬,介绍二氧化碳生物固定和转 化研究领域的最新进展。 二氧化碳是温室气体,也是重要的生物制造原料 我们每时每刻都在呼出的二氧化碳,是生命代谢的产物,也是自然界碳循环的关键一环。这种看不见的 气体,也是全球气候治理的焦点。 二氧化碳如同覆盖在地球表面的"保温被",适量存在能将地球表面平均温度维持在15摄氏度左 ...
