据澳大利亚广播公司(ABC)报道:在美国能源部大湖生物能研究中心的生物化学家约翰·拉尔夫及其同事进行的一项研究中,他们在中药当归的根部找到一种天然形成的酶,酶中的一种基因可降低分解木素的难度。拉尔夫表示,他们能利用这种基因对树木进行基因改造,使木素的分子结构发生改变,使其更容易被工业化学品分解,如果采用含有这种木素的木材造 According to the ABC report, in a study by biochemist John Ralph of the US Department of Energy’s Great Lakes Bio-Energy Research Center and colleagues, they found a naturally occurring enzyme at the root of Chinese angelica , A gene in the enzyme can reduce the difficulty of the decomposition of lignin. Ralf said they can use the gene to genetically engineer trees, changing the molecular structure of the lignin, making it more susceptible to decomposition by industrial chemicals. If wood is made from wood that contains the lignin
