日前,来自加拿大约克大学和法国马赛第一大学的研究人员在《自然-化学生物学》杂志上报告称,他们拓展开发了第二代生物燃料。研究发现,有一种酶家族能够把在自然中“难以消化”的生物质降解为自身糖的成分。第一代生物燃料对于寻找可再生能源和能源安全产生了一定影响,特别是利用自然界中“易于消化”的生物质如玉米淀粉来制造生物乙醇。但这种方法需要大量能源作物,由此占用了宝贵的可耕土地,进而危及到食品价格的稳定,还限制了生 Recently, researchers from York University in Canada and Marseilles First University in France reported in the journal Nature - Chemical Biology that they have expanded the development of second-generation biofuels. The study found that there is a family of enzymes that can degrade the “hard-to-digest” biomass into its own sugar in nature. The first generation of biofuels had an impact on the search for renewable energy and energy security, especially the use of bio-ethanol, such as corn starch, which is “easily digestible” in nature. However, this method requires a large amount of energy crops, thus occupying valuable arable land, which in turn jeopardizes the stability of food prices and also limits births
