Over one hundred years ago Robert Koch made one of the most important conceptual and technological break- throughs in the history of microbiology with the discovery of methods for the production of solid nutrient media and the ability to isolate pure cultures of microorganisms. The importance of this discovery to advances in medical, agricultural and industrial microbiology would be hard to overestimate. The dividends these techniques returned have positively affected the lives of nearly everyone on the planet. The training of generations of microbiologists has been based, to a significant degree, on the investigation of the properties of pure cultures and the elucidation of the properties of these organisms one at a time. As productive as this strategy has been it perpetuates an astonishingly erroneous conception. In fact, pure cultures are absent or virtually so in nature. A science based largely on an artifact.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
