Proteose Peptone B is obtained by enzymatic hydrolysis of protein, rich in proteases, peptide and free amino acids. It is manufactured under controlled conditions while maintaining degree of hydrolysis so as to retain its nutritive value. It provides superior nutrition for fastidious organisms including pyogenic cocci.
