一、前言生物工程,又称生物技术或叫生物工艺学.它是应用生物学的理论、工程学的原理,以及现代化的计算机技术等,对生物体系本身进行定向改造、培育新的生物类型和生产人类有用的各类物质的一门新兴尖端科学技术. 生物工程研究领域十分广泛,目前,一般认为它包括基因工程(DNA重组等)、细胞工程学(杂交瘤技术、原生质培养和细胞杂交等)、酶工程学(利用酶类将一种物质转化为另一类物质等) 和发酵工程学(利用微生物发酵将各种原料转化为不同的产品) 四个方面.自70年代崛起以
I. Introduction Bioengineering, also known as biotechnology or biotechnology, is the application of biological theory, engineering principles, and modern computer technology, the biological system itself directed innovation, cultivate new biological types and Bio-engineering research is very broad, at present, it is generally believed that it includes genetic engineering (DNA recombination, etc.), cell engineering (hybridoma technology, protoplast culture and cell hybridization, etc. ), Enzyme engineering (using enzymes to transform one substance into another), and fermentation engineering (using microbial fermentation to transform various raw materials into different products). Since the rise of the 1970s
