e screened for useful products and grown up on a large enough scale to produce and extract the desired product and then to subject the product to critical evaluation. 要想获得有用的产品，就必须对这些生物进行筛选并且要大规模地进行培养让它们生长，这样才能提取并生产出所需求的产品，然后再对产品进行鉴定评估。 However, a major hindrance to the full exploitation of this capacity is the availability of suitable screening procedures which can identify the necessary product, especially in the presence of culture medium constituents. 但是，阻碍这个能力（这项技术）充分开发的主要问题就是能否找到合适的筛选方法分离鉴定必需的产品，尤其是在培养基存在的情况下。 1 In the search for new microanisms from the environment for biotechnological processes there are normally three types of option available。 these involve the choices of habitat for sampling, the physical separation procedures for separating out the desired microanism and the choice of method to achieve selection which in most in most cases involved enrichment cultures. 从环境中筛选用于生物技术工艺的新的微生物的过程中往往存在着三种选择。 这些选择包括： 样品生 长环 境的选择； 分离出目标生物的物理分离方法的选择； 获得 所选产物 的 方法 ，而这些方法大多情况下都涉及到富集培养。 1 Large numbers of isolates or mutants can now be plated out, exposed to a wide range of environmental conditions and the responses recorded automatically over any time period using television monitoring and puter control. 现在可以将大量的单体分离物或突变型从平。
