一、行业与行业间的划分将日趋模糊目前,许多从事医药、农业、环境、能源等方面生产的企业,正在从事生物化工生产。特别是某些从事传统化工行业的生产厂家,也纷纷涉足生物化工领域。如杜邦公司,长期以来主要从事有机化工和聚合材料的生产,现在正加大生物化工的开发力度,已开发成功了生物法生产1,3-丙二醇工艺,并正在 I. The division between industries and industries will become increasingly blurred At present, many companies engaged in the production of medicine, agriculture, environment, and energy are engaged in biochemical production. In particular, some manufacturers engaged in the traditional chemical industry have also set foot in the biochemical field. DuPont, for instance, has long been mainly engaged in the production of organic chemicals and polymer materials. It is now increasing the development of biochemicals and has successfully developed the biological process for the production of 1,3-propanediol.
