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. 要想獲得有用的產(chǎn)品,就必須對這些生物進行篩選并且要大規(guī)模地進行培養(yǎng)讓它們生長,這樣才能提取并生產(chǎn)出所需求的產(chǎn)品,然后再對產(chǎn)品進行鑒定評估。 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,阻礙這個能力(這項技術(shù))充分開發(fā)的主要問題就是能否找到合適的篩選方法分離鑒定必需的產(chǎn)品,尤其是在培養(yǎng)基存在的情況下。 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. 從環(huán)境中篩選用于生物技術(shù)工藝的新的微生物的過程中往往存在著三種選擇。這些選擇包括: 樣品生 長環(huán) 境的選擇; 分離出目標生物的物理分離方法的選擇; 獲得 所選產(chǎn)物 的 方法 ,而這些方法大多情況下都涉及到富集培養(yǎng)。 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. 現(xiàn)在可以將大量的單體分離物或突變型從平
