hen we try to study the bacterial flora of the body, soil, water, or just about any environment, e realize that bacteria exist in natural environments as mixed populations. It is only in very re instances that they occur as a single species. are cultures are required to study the cultural, morphological, and physiological aracteristics of an individual organism. Several methods for obtaining pure cultures are ailable to the microbiologist today. Two commonly used methods are streak plate methods and pour plate methods. oth types of procedures involve repeatedly diluting the cells in a sample to an end point nere a single cell divides giving rise to single pure colony. The colony is therefore assumed be the identical progeny of the original cell and can be picked and used for further study of e bacterium. eaking e drop of bacterial solution contains millions of cells. To identify a species, individual strain ve to be grown separately, starting from a single cell. The most commonly. used method t ate strain originating from a single cell is called the streaking method. There are severa erent ways to streak a plate.

There are so many microbes in a single mL of culture, it is very difficult to perform one dilution to produce countable cells. Microbiologists need to perform a dilution series, where multiple dilutions are performed in sequence to arrive at the correct dilution. Dilutions are cumulative. Multiple the series of dilutions together to find the final dilution value. If 3 serial dilutions are performed, each with a value of 0.01, what is the cumulative dilution? Express your answer as an exponent, e.g. 0.1 would be 1e-1 and 0.01 would be 1e-2
