Proteose Peptone Rice Agar

Proteose Peptone Rice Agar

This is a medium for the isolation and identification of Group B streptococci. The principal of the medium is based on the ability of group B streptococci to produce unique orange/red pigmented colonies when incubated anaerobically, particularly on media containing starch products. This medium is non-selective so other organisms will grow on this medium but they do not produce the characteristic pigment.
