  • examples of growth on EMB

    Food products provide rich environments for microbial growth. In this lab, students examine microorganisms found in milk, poultry, and other foods using serial dilution and standard plate count techniques. The lab emphasizes food safety, microbial indicators, and the importance of proper food handling.

    Typical growth on EMB. Left - a non-lactose fermentor. Right - a vigorous lactose fermenter such as E. coli produces a characteristic green sheen.  BioLibreTexts. https://bio.libretexts.org/Courses/City_College_of_San_Francisco/Microbiology_Lab_Manual_%28Miraglia%29/01%3A_New_Page/1.12%3A_Completion_of_the_ID_Project
