  • Introduction 

    The objective of this study was to detect mutations in test strains (usually uses Salmonella typhimurium or Escherichia coli) caused by the test substance. Test strains are exposed to the test substance.  If test substance causes mutation,  test strains are able to form colonies that are visible to the human naked eyes on medium.  We will infer from the growth of colonies that whether test substance is a possible carcinogen.
