All I could find is that it is a peptic digest of animal tissue. There
are three different ones from Difco. Proteose Peptone Difco, Proteose
Peptone No.2 Difco and Proteose Peptone No.3 Difco.
According to the manual No.3 is the best of the three for nutrition in
culturing fastidious organisms.
Sorry, I don't know of any substitutes for it.
