Phenylethyl Alcohol (PEA) Agar

The video tutorial explains the use of Peagler, a selective medium containing phenylethyl alcohol, which inhibits the growth of gram-negative bacteria while allowing gram-positive bacteria to thrive. It highlights the importance of Peagler in identifying bacterial gram reactions, noting that it is not bactericidal but rather inhibits growth. The tutorial also discusses the use of Peagler alongside other tests like the Gram stain and MacConkey Agar for bacterial identification. The conclusion emphasizes Peagler's role in determining gram reactions based on bacterial growth patterns.
