Buffered Peptone Water (BPW) Plus is used as diluent and nutritive enrichment broth for the
resuscitation and growth of a wide variety of microorganisms including
Principle
The special selection of peptones allows a very high level of nutritivity to ensure the best recovery. In combination with the phosphate buffer's maintenance of a steady pH and osmotic balance, thanks to the presence of chloride sodium, BPW Plus offers favorable conditions for the growth of a wide range of microorganisms from a variety of matrices.
