在实验室中对纯培养物的研究提供了微生物代谢能力的惊人多样性，并为我们理解自然界中的关键转化过程奠定了基础。纯培养研究也是微生物生物化学和分子生物学研究的先决条件。然而，想要了解微生物在自然系统中的作用，需要认识到微生物通常不是以纯培养物的形式存在，而是每个细胞都必须与其他微生物或大型生物合作或竞争。纯培养物是实验室的人工制品，除了某些例外，如某些与高等生物直接合作的微生物。从纯培养物研究中获得的信息只能非常谨慎地用于理解自然界中微生物的行为。相反，需要在微观尺度上对非生物和生物生命条件进行详细分析，以正确评估微生物在其自然栖息地中的代谢活动和需求。
The study of pure cultures in the laboratory has provided an amazingly diverse diorama of metabolic capacities among microorganisms, and has established the basis for our understanding of key transformation processes in nature. Pure culture studies are also prerequisites for research in microbial biochemistry and molecular biology. However, desire to understand how microorganisms act in natural systems requires the realization that microorganisms don t usually occur as pure cultures out there, but that every single cell has to cooperate or compete with other microor macroorganisms. The pure culture is, with some exceptions such as certain microbes in direct cooperation with higher organisms, a laboratory artifact. Information gained from the study of pure cultures can be transferred only with great caution to an understanding of the behavior of microbes in natural communities. Rather, a detailed analysis of the abiotic and biotic life conditions at the microscale is needed for a correct assessment of the metabolic activities and requirements of a microbe in its natural habitat.
