PHENYLETHYL BLOOD AGAR BASE (ANAEROBIC)

Phenylethyl alcohol is a chemical agent that exhibits inhibitory action against gram-negative and certain gram-positive bacteria. Phenylethyl Blood Agar Base (Anaerobic) is used for the isolation of obligate anaerobic gram-positive and gram-negative bacteria. Supplementation of medium with L-cystine permits growth of certain thiol-dependent or sulphur containing amino acids- requiring bacteria and fastidious Streptococci. This medium inhibits facultative anaerobic gram-negative bacteria such as E. coli and Proteus species.
