石油烃类原料是不可再生资源,因而用来源广阔的碳水化合物原料代替石油原料,生产合成化学品、可降解材料、生物能源等,成为国内外生物产业界研发的热门课题。最近由于技术的进展,生物合成的基础原料和技术路线出现了一些新的动向,如合成生物降解材料、1,3-丙二醇、乙二醇、生物燃料等。
As a non-renewable resource, petroleum hydrocarbon raw materials have become a hot topic in the bioindustry research at home and abroad because they use a wide range of carbohydrate raw materials instead of petroleum raw materials to produce synthetic chemicals, degradable materials and bio-energy sources. Recently, due to advances in technology, some new trends have emerged in the basic raw materials and technical routes of biosynthesis, such as synthetic biodegradable materials, 1,3-propanediol, ethylene glycol, biofuels and the like.
