“With OxyPRAS Plus media, you get better growth than traditional non-PRAS media. Anaerobes normally grow slowly and some produce such small colonies that they are difficult to work with. Because the same anaerobes grow more quickly and abundantly on the commercial PRAS media, it is much easier to work with them.”
Timothy R. Cassity, Ph. D.
