Koch initially experimented with growing bacteria on the cut surfaces of potatoes. Media preparation and sterilization, Aseptic technique & pure culture concept. Introduction. In natural environments, microorganisms usually exist as mixed populations. However, if we are to study, characterize, and identify microorganisms, we must have the organisms in the form of a pure culture. . Micr. ob. ial Growth. Mrs. . Amany. Ahmed . Niazy. History.

Observation. For centuries, people based their beliefs on their interpretations of what they saw going on in the world around them without testing their ideas to determine the validity of them.. The continued survival of living organisms including humans depend on sustainable communities. . Understandings:.
