病原微生物也是一种重要的生物资源,它的保藏不仅有利于重现已经做过的实验,证实发现新的菌(毒)种,而且也是研究、推广、开发和实际应用科研成果的基础。保藏的菌(毒)种有的是开发利用的对象,有的是悉心研究的成果,有从自然界分离得到的,有经生物技术修饰改造获得的,都有着极大的研究价值和 Pathogenic microorganisms are also important biological resources. Their preservation not only helps to reproduce the experiments that have been done, but also confirms the discovery of new species of bacteria and it also serves as a basis for research, promotion, development and practical application of scientific research. Some kinds of bacteria (poison) are the object of development and utilization, and some are the results of careful research. They have been isolated from nature and have been modified through biotechnological modification and have great research value.
