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(学名:Angelica sinensis)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的基因改造,使能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纸,所需耗费的时间更短,所需达到的温度也更低, According to the ABC report, in a study by biochemist John Ralph at the US Department of Energy’s Great Lakes Bio-Energy Research Center and colleagues, they were found at the roots of Angelica sinensis A naturally occurring enzyme, a gene in the enzyme that reduces the difficulty of breaking down lignin. Ralf said they can use this gene to genetically engineer trees, change the molecular structure of the enabling lignin to make it more susceptible to decomposition by industrial chemicals, and if wood is used to make paper that contains the lignin It takes less time and requires less temperature to reach,
