   DNA fingerprinting used to identify the similarity between the strains of microbes you use.
   As you might already know, DNA fingerprinting result is the same as electrophoresis which produce bands of DNA fragment on a gel (usually Agarose gel).
   By comparing the similarity between your strains and use a DNA marker as control and a result from a Type Strain as comparison, you can identify your strains.
   If 2 strains provide almost similar result, you can assume that they belong to one taxa or if one of your strain have similar result to your Type Strain DNA, you can assume that your strain is belong to that type strain’s group.

   Also, the result from DNA fingerprinting can be used as a Data in Numerical Taxonomy to construct dendogram which show relationship between your strains.
