生物转化在化学工业中的应用及前景

化学工业的可持续发展性 ,推动了生物法生产化学品的研究。生物学体系有许多吸引人的特征 ,包括多功能性、底物选择性、立构选择性、化学选择性、对映选择性以及在室温和常压下的催化作用。然而 ,生物法面临的挑战是与化学法的成本竞争 ,这是因为目前商业方法的固定资产是相当高的。化学工业很可能利用生物技术从现有原料中提取高附加值产品以及对副产物或废料进行处理 ,要达到工业生产所需的速率、性能和产量。在工艺和产品方面都优于传统化学法的生物法将得到更加广泛的应用。

Application and prospect of bioconversion in chemical industry

At present, researchers in the chemical industry are exploring the use of renewable feedstock to improve sustainability, and this prompts the exploration of bioprocesses for the production of chemicals to a great extent. Biological systems have many attractive features that include versatility, substrate selectivity, regioselectivity, chemoselectivity, enantioselectivity and catalysis at ambient temperatures and pressures. However, bioprocesses are facing a challenge of cost competitiveness with chemical processes because capital assets associated with the existing commercial processes are high. The chemical industry will probably use biotechnology with existing feedstock and processes to extract higher values from existing feedstock, and to treat the by products or waste streams of the process. Bioprocesses offer either a process or a product advantage over traditional chemical routes. Bioprocesses will become more widely used in this decade. [
