生物英语求翻译 谢谢
Having selected the organism , growth must take place under conditions that will maximize enzyme production .Extracellular enzymes have specific advntages over intracellular enzymes since their production does not require costly cell disruption techniques ; furthermore , extracellular enzymes are present in a relatively pure form in the culture liquid whereas intracellular enzymes need more complicated methods of separation and purification . Extracellular enzymes make up the bulk of industrial microbial enzyme production but intracellular enzymes are finding an increasingly important role as diagnostic enzymes in medicine and industry.

答案

选定生物,且生长条件能使酶产量最大化.
细胞外酶比细胞内酶有很大的优势,特别是产量高于后者,而且生产不需要昂贵的破细胞技术；另外,细胞外酶一般相对纯净,而细胞内酶需要复杂的工序来分离和纯化.
现在酶的工业化生产主要是细胞外酶,但是最近发现在医学和工业领域,细胞内酶在诊断功能上扮演越来越重要的功能.
